Precum is what emerges when you are aroused. As the dick gets hard, out comes that familiar clear and often inconspicuous fluid known as precum. Precum is the 9pm fireworks of sexual activity, it’s not the main event, it’s not necessarily that exciting and it often goes unnoticed.
But what does precum do? Does it serve a purpose at all? More importantly is it safe to play with? Allow us to answer some commonly asked questions about precum.
Precum is produced by the ‘Cowper’s Glands’, two small glands near the prostate. It is released upon arousal to neutralize the acidity of the urethra. An evolutionary explanation of precum goes as follows: Precum acts as a bodyguard for sperm, the clear viscous fluid ensures that sperm gets from its house (the prostate) to the club (the vagina) free of damage or injury. Once safely in the vagina, sperm can go forth and make babies. Thank you precum, you’re the best!
Regardless of whether you are trying to procreate or not, the precum will arrive. What we mean by this is that it doesn’t matter if you are having vaginal, anal or oral sex. For this reason we need to have a think about whether or not precum poses a risk for HIV infection when men have sex with men.
Research has confirmed that precum does indeed carry HIV. Whether precum carries enough HIV to cause infection is a research question that needs to be studied further. This said, a study was conducted in 2003 which examined the efficacy of delayed condom application in preventing HIV transmission among a population of gay and bisexual men. The study confirmed that men who applied condoms midway through anal intercourse rather than at the start of intercourse were approximately 5 times more likely to acquire HIV than those who applied condoms at the beginning. It is not entirely clear if this risk was primarily due precum or some other mechanism, however precum is likely to be in the mix. Additionally, it is important to note that if someone with HIV is on treatment with an undetectable viral load, the risk will be greatly reduced.
This means that if you are having anal sex with a casual partner it’s a good idea to use a condom from the start of intercourse. Research shows that men who delay condom application during anal sex are at a higher risk of acquiring HIV than those who don’t. As modern gay men we are lucky to have an array of risk reduction strategies at our disposal but condoms remain the most effective way of preventing HIV when used correctly. Use a condom from start to finish and avoid any risk of acquiring HIV from precum!
