Preparation: What Actually Matters
Safe anal sex for gay men starts with preparation, and the preparation conversation is often more complicated in people’s heads than it needs to be in practice. The main concern for most men is cleanliness. The practical answer is: the rectum does not permanently store faeces. The lower rectum is generally clear unless a bowel movement is imminent. For most men, a shower, emptying the bowel before play, and avoiding a meal 1-2 hours before is sufficient preparation for sex without penetration beyond the lower rectum.
For more thorough preparation or deeper penetration: a simple anal douche or bulb syringe with lukewarm water is the most common approach. Fill, insert gently, release, and repeat until the water runs clear. Use lukewarm water only, never soap, never tap water at significant pressure, never enemas with additives. The rectum absorbs water and compounds introduced into it.
Douching: How to Do It Correctly
A bulb syringe holds about 150-200ml of water. This is enough to clean the lower rectum. Fill with lukewarm water, insert the nozzle gently with a small amount of water-based lube, squeeze slowly, retain briefly, and release over the toilet. Repeat 2-3 times until the water is clear.
Do not use a full enema bag with high volume. Do not add soap or other compounds to the water. Do not douche immediately before sex as the tissue needs a short recovery period after water contact.
Over-douching disturbs the rectal microbiome and can make the tissue more vulnerable. It is not something to do multiple times per day.
Lube: The Most Important Variable
The single factor that makes the biggest difference to comfort and safety in anal sex is lube quality and quantity. The anal canal does not self-lubricate. Without sufficient lubrication, microtears occur in the delicate tissue. Microtears increase STI transmission risk and cause pain.
Use more lube than you think is necessary. Apply it to both the penetrating partner and the external anal area. Reapply during the session if there is any sensation of drag or friction. There is no such thing as too much lube for anal sex.
For lube types and which to use in different situations, see the Manatomy lube guide for men.
Protection and STI Risk
Receptive anal intercourse has the highest per-act STI transmission risk of any sexual activity, including HIV, gonorrhoea, chlamydia, and syphilis. Condoms, when used consistently and correctly, significantly reduce transmission risk for all of these.
PrEP (pre-exposure prophylaxis) is available in Australia and is highly effective at preventing HIV transmission when taken as directed. It is not a replacement for testing and does not protect against bacterial STIs. Regular STI testing (every 3 months for men with multiple partners) is part of practising safe anal sex in the full sense of the term.
Positions for Comfort
Positions that allow the receiving partner control over the depth and pace are most comfortable for first-time or less experienced anal sex.
Riding: receiving partner on top, controls all movement and depth. This position gives the most autonomy to the person receiving and is often recommended for firsts.
Missionary with elevated hips: pillow under the lower back changes the angle and can reduce strain. The Inflatable Fuck Pillow is designed for exactly this purpose, allowing the angle to be set precisely.
Doggy style: the angle can be very comfortable but gives the penetrating partner more control, which is worth factoring in.
Pain: What Is Normal and What Is Not
Some sensation during anal sex is normal. Pain that causes you to want to stop is a signal to stop. The distinction between the mild stretch of penetration and actual pain is worth paying attention to rather than pushing through.
If penetration is consistently painful: more lube and slower approach. If discomfort persists, try a different position. If pain is persistent across multiple sessions regardless of preparation, talking to a doctor about whether there is an underlying anatomical reason is worthwhile.
After-Sex Care
Post-sex, the anal tissue has been stretched and stimulated. A gentle warm wash is sufficient. If there is minor bleeding, this is usually a minor tear and typically resolves within a day. Significant bleeding warrants medical attention.
Rest is natural after extended anal activity. For solo toy use, see the butt plug guide and dildo guide for care-specific information.
