Being sexually healthy involves considerably more than maintaining an erection or having a strong libido. It includes consent, communication, contraception, STI prevention, testing, vaccination and recognising physical changes that deserve medical attention.
Sexual health is relevant whether a man has sex with women, men or partners of different genders. The appropriate protection and testing plan depends on the activities involved, the anatomy exposed and each partner’s health—not solely on sexual identity.
Taking responsibility does not mean expecting sex to be risk-free. It means understanding the possible risks, communicating honestly and making informed decisions with every partner.
1. Consent Is Required Every Time
Consent must be freely and clearly given for each sexual activity. Dating, marriage, previous sex or going home together does not create automatic permission.
A partner can consent to one activity while declining another. For example:
- Kissing does not imply consent to penetration
- Vaginal sex does not imply consent to anal sex
- Sex with a condom does not imply consent without one
- Consent on one occasion does not apply permanently
- Consent can be withdrawn after sexual activity begins
Someone who is asleep, unconscious, significantly intoxicated, under the applicable legal age or being pressured cannot provide meaningful consent.
Check in when a partner becomes quiet, tense or uncertain. Questions such as “Does this feel comfortable?” or “Would you like to continue?” demonstrate attentiveness rather than insecurity.
Consent applies equally to men. A man can decline any activity, stop after becoming aroused and withdraw consent at any time. An erection is a physical response—not proof of consent.
2. Discuss Sexual Health Before Sex
A sexual-health conversation may feel uncomfortable, but it is easier than managing an unexpected infection, pregnancy or disagreement later.
Partners should discuss:
- When they were last tested for STIs
- Whether they have had new partners since testing
- Which tests were performed
- Condom or barrier use
- Contraception
- Whether the relationship is exclusive
- Any known infection
- HIV prevention
- Activities either person does not want
- What should happen if protection fails
“I was tested” is incomplete information. An STI check may not include every infection or every relevant site.
A urine test, for example, will not necessarily detect an infection in the throat or rectum. Testing should reflect the types of sex someone has had.
3. Many STIs Cause No Symptoms
A penis that looks and feels healthy does not prove that someone has no STI.
Chlamydia, gonorrhoea, HIV, syphilis, hepatitis and human papillomavirus can sometimes be present without noticeable symptoms. Testing is therefore important after relevant exposure or when recommended for an individual’s risk profile.
Possible STI symptoms in men include:
- Discharge from the penis
- Burning during urination
- Genital sores or blisters
- An unexplained rash
- Testicular pain or swelling
- Rectal pain, discharge or bleeding
- Persistent throat symptoms following oral exposure
- Pain during sex
- Swollen lymph nodes
- Flu-like symptoms after a possible exposure
Symptoms may disappear even when an infection remains. The NHS notes that early syphilis symptoms can be mild, difficult to notice and may resolve without eliminating the infection.
Avoid sexual contact and obtain professional advice when symptoms or a known exposure occur.
4. Testing Should Match Your Sexual Activities
There is no single STI-testing schedule for every man. Recommended frequency depends on partners, sexual activities, condom use, previous infections, HIV status and local disease patterns.
Testing may involve:
- Urine samples
- Blood tests
- Urethral swabs
- Throat swabs
- Rectal swabs
- Swabs from a sore or lesion
Tell the healthcare professional whether you have had oral, vaginal or anal sex and whether you were the inserting or receiving partner. This information helps determine which body sites should be tested.
According to CDC STI-testing guidance, sexually active gay and bisexual men and other men who have sex with men should generally be tested at least annually for syphilis, chlamydia and gonorrhoea. Testing every three to six months may be appropriate for those with multiple or anonymous partners or other increased risks.
Heterosexual men at low risk do not necessarily need every STI test annually, but testing may be appropriate after:
- A new partner
- Multiple partners
- Condomless sex
- A partner’s positive result
- STI symptoms
- A condom failure
- Sex in a higher-prevalence setting
- Sharing injection equipment
- Another relevant exposure
Follow local Malaysian clinical guidance and personalised advice from a qualified healthcare professional.
5. Use Condoms Correctly
External condoms can reduce the risks of pregnancy and many STIs when used consistently and correctly.
For each act:
- Check the expiration date and wrapper.
- Open the packet carefully.
- Place the condom on before genital, oral or anal contact.
- Pinch the tip and roll it to the base of the erect penis.
- Use compatible lubricant where needed.
- Stop and replace it if it breaks or slips.
- Hold the base during withdrawal.
- Use a new condom before another act.
Never reuse a condom. Replace it when moving from anal to vaginal sex or when sharing a toy between partners or body areas.
Do not use two external condoms together, and do not combine an external condom with an internal condom. Extra layers create friction and may increase the likelihood of failure.
Condoms reduce risk but do not offer complete protection against infections spread through skin contact, such as herpes, syphilis and HPV when affected areas are not covered.
For more guidance, read ActivHomme’s article on safer sex.
6. Choose a Compatible Lubricant
Lubrication can improve comfort and reduce friction that may damage skin or condoms.
With latex condoms, use a water- or silicone-based lubricant. Avoid:
- Petroleum jelly
- Body lotion
- Massage oil
- Cooking oil
- Baby oil
- Other oil-based products
Oil can weaken latex and make breakage more likely.
Anal tissue does not naturally produce sufficient lubrication for penetration, so additional lubricant is particularly important. Apply more when needed rather than continuing through pain or excessive friction.
If a product causes burning, itching or swelling, stop using it. Fragranced, warming or numbing products may irritate sensitive tissue.
7. Condoms Are Not the Entire Contraception Plan
When penis-in-vagina sex occurs, pregnancy is possible. Men should participate actively in contraception discussions rather than treating pregnancy prevention as solely their partner’s responsibility.
Ask:
- Which method is being used?
- Has it been used correctly?
- Will a condom also be used?
- What would both people do if protection failed?
- Is emergency contraception accessible?
- Are both partners comfortable with the pregnancy risk?
Withdrawal is less dependable than condoms or established contraceptive methods. Timing can be difficult, and withdrawing does not protect against STIs.
Never interfere with another person’s contraception, pressure someone to avoid protection or remove a condom secretly. Consent to sex with a condom is not consent to sex without one.
8. Vaccination Can Prevent Certain Infections
Vaccination can prevent some infections associated with sexual contact.
HPV vaccination
Human papillomavirus is extremely common. Certain types can cause genital warts and cancers affecting the penis, anus and throat.
Condoms reduce HPV exposure but cannot cover every potentially affected area. The CDC explains that condoms may lower HPV risk without providing complete protection.
Ask a healthcare professional whether you have completed the recommended HPV vaccination schedule. Eligibility and catch-up recommendations vary by age and country.
Hepatitis vaccination
Hepatitis B can spread through sexual contact and blood. Hepatitis A may also be relevant for some sexual practices, particularly oral–anal contact.
Review your vaccination history with a healthcare professional, especially if you:
- Have multiple partners
- Have sex with men
- Have another STI
- Live with HIV
- Inject drugs
- Have chronic liver disease
- Travel to areas with higher prevalence
9. Understand HIV Prevention Options
Condoms remain an important HIV-prevention tool, but additional methods are available.
PrEP
Pre-exposure prophylaxis, or PrEP, is medication used by people without HIV who may be exposed through sex or injection drug use.
The CDC states that PrEP greatly reduces the chance of acquiring HIV when taken as prescribed. It does not prevent pregnancy or other STIs, so condoms and testing may still be appropriate.
PEP
Post-exposure prophylaxis, or PEP, is emergency medication considered after a possible HIV exposure. It must be started quickly—generally within 72 hours—and earlier is better.
Seek urgent medical advice rather than waiting for symptoms or a routine appointment.
Treatment as prevention
A person with HIV who takes effective treatment and maintains an undetectable viral load does not sexually transmit HIV. This is often described as U=U: undetectable equals untransmittable.
HIV prevention should be discussed without stigma. Testing, PrEP and treatment are healthcare tools—not judgements about someone’s character.
10. Oral Sex Is Not Risk-Free
The likelihood of HIV transmission through oral sex is much lower than through vaginal or anal sex, but oral sex can transmit:
- Gonorrhoea
- Chlamydia
- Syphilis
- Herpes
- HPV
- Hepatitis
- Some intestinal infections during oral–anal contact
External condoms can be used for oral sex on a penis, while dental dams can provide a barrier for oral contact with a vulva or anus.
Consider throat testing after relevant exposure because a urine test will not detect a throat infection.
ActivHomme’s guide to comfortable oral-sex positions includes additional information about consent, breathing and barrier use.
11. Clean Toys and Change Barriers
Sex toys can transfer body fluids and microorganisms between partners or body areas.
Follow the manufacturer’s cleaning instructions and consider:
- Whether the material is non-porous
- Whether the toy is waterproof
- Which lubricants are compatible
- Whether a condom can be placed over it
- Whether it has cracks or damage
- How it should be dried and stored
If a toy is shared, clean it and place a new condom over it for each user where appropriate. Change the condom before moving the toy from anal to vaginal use.
Never insert a toy without a flared base into the rectum. Objects without a secure base can become difficult to remove and may require emergency care.
12. Pay Attention to Testicular Changes
Men should be familiar with the usual appearance and feel of their testicles. This does not require obsessive daily checking.
Seek medical assessment for:
- A new lump
- Persistent swelling
- A change in size, shape or texture
- A feeling of heaviness
- Ongoing discomfort
- A firm area within a testicle
Sudden, severe testicular pain—particularly with swelling, nausea or a testicle sitting unusually high—requires emergency assessment. It may indicate testicular torsion, in which the blood supply becomes twisted.
Do not assume testicular pain is always an STI or exercise injury.
13. Do Not Ignore Persistent Erectile Difficulties
Occasional difficulty obtaining or maintaining an erection is common. Stress, tiredness, alcohol, relationship concerns and performance anxiety may all contribute.
Persistent erectile dysfunction can also be associated with:
- Diabetes
- High blood pressure
- High cholesterol
- Cardiovascular disease
- Medication
- Depression or anxiety
- Hormonal problems
- Nerve or pelvic injury
Repeated difficulty deserves medical assessment rather than unregulated supplements bought online.
Do not combine erectile-dysfunction medication with nitrates or recreational nitrites such as “poppers”; the combination can cause a dangerous drop in blood pressure.
Food supports general cardiovascular health, but watermelon, garlic and other foods should not be described as natural substitutes for prescribed erectile-dysfunction treatment.
14. Alcohol Can Affect Safety and Sexual Function
Alcohol may reduce inhibitions, but larger quantities can interfere with erections, orgasm, judgement and condom use.
It can also make it more difficult to:
- Recognise discomfort
- Communicate clearly
- Respect boundaries
- Apply a condom correctly
- Remember what was agreed
- Provide meaningful consent
There is no reliable number of drinks that guarantees someone remains capable of consenting. If a person cannot understand, decide or communicate clearly, sexual activity should not proceed.
Recreational drugs may create additional risks through impaired judgement, interactions with medication and prolonged erections.
An erection lasting four hours or longer is a medical emergency.
15. Diet and Exercise Support Health—Not Instant Performance
A diet built around vegetables, fruit, whole grains, adequate protein and unsaturated fats supports cardiovascular and metabolic health. Regular physical activity, sufficient sleep, avoiding smoking and limiting alcohol may also support sexual function.
These habits can reduce the likelihood of health problems associated with erectile dysfunction, but their effects are gradual.
Be cautious of claims that a particular food can:
- Raise testosterone immediately
- Work like sildenafil
- Guarantee stronger erections
- Produce instant libido
- Correct infertility
- Cure erectile dysfunction
Low testosterone can only be diagnosed through appropriate symptoms, medical assessment and correctly timed blood tests. Libido alone cannot establish the diagnosis.
16. Seek Help for Pain, Discharge or Urinary Changes
Arrange medical care for:
- Penile discharge
- Genital sores, blisters or warts
- Pain during urination
- Blood in urine or semen
- Persistent pelvic or genital pain
- Pain during ejaculation
- Difficulty urinating
- A weak or interrupted urine stream
- Significant penile curvature with pain
- Persistent foreskin problems
- Repeated erectile or ejaculation difficulties
Do not use leftover antibiotics or another person’s medication. The wrong treatment may delay diagnosis and contribute to antimicrobial resistance.
The Bottom Line
Sexually active men should think beyond performance. Good sexual health involves consent, communication, condoms, appropriate testing, contraception and timely medical care.
Use a new condom for every act, select compatible lubricant and discuss contraception rather than leaving responsibility entirely to a partner. Make sure testing reflects the types of sex you have had, including possible throat or rectal exposure.
Review your HPV and hepatitis vaccination history and discuss PrEP when HIV exposure is a realistic possibility. Seek urgent care after a possible HIV exposure if PEP may be needed.
Finally, do not ignore persistent erectile difficulties, testicular changes, discharge, sores or pain. Sexual-health concerns are ordinary healthcare matters, and addressing them promptly protects both you and your partners.

Frequently Asked Questions
How often should sexually active men get tested for STIs?
It depends on partners, activities and risk. Men who have sex with men are generally advised to test at least annually and sometimes every three to six months. Other men should seek personalised advice after new partners, condomless sex, symptoms or known exposure.
Can a man have an STI without symptoms?
Yes. Chlamydia, gonorrhoea, HIV, syphilis and other infections may cause no obvious symptoms. Testing is the only reliable way to identify many infections.
Does a urine test detect every STI?
No. Urine testing will not necessarily detect infections in the throat or rectum. Tell the healthcare professional which types of sex occurred so the correct sites can be tested.
Should condoms be used in a monogamous relationship?
That is a joint decision based on STI testing, exclusivity and pregnancy prevention. Do not assume monogamy or negative STI status without discussing it.
Is PrEP only for gay men?
No. PrEP may be appropriate for anyone without HIV who could be exposed through sex or injection drug use. A healthcare professional can assess individual circumstances.
Can diet naturally cure erectile dysfunction?
No particular food cures erectile dysfunction. A balanced diet supports cardiovascular health, but persistent erection problems require proper assessment.
When is testicular pain an emergency?
Sudden, severe testicular pain—especially with swelling, nausea or an unusually positioned testicle—requires immediate emergency care because testicular torsion is possible.
Does contraception remain the woman’s responsibility?
No. Men should participate in discussions about condoms, contraception, emergency plans and pregnancy intentions. Reproductive responsibility should be shared.
