Cocksucking is a very low risk activity in relation to HIV transmission but some other STIs are readily transferred during oral sex.
HIV is a fragile virus and is readily digested and neutralised by enzymes in saliva. Similarly, if HIV in cum is swallowed, acids and digestive enzymes in the stomach destroy the virus. Consequently, in the absence of blood, it is very difficult to get HIV from having your cock sucked or from sucking a guy’s cock. However, extensive bleeding in the mouth can increase the risk to the top.
Damage or inflammation that breaks down the protective barriers in the mouth can greatly increase your risk of getting HIV from semen and pre-cum. Such damage could be caused by:
- Ulcers, throat infections, gingivitis and other sores in the mouth;
- Flossing or vigorous teeth brushing prior to sex;
- Recent dental work;
- Recently eating food that cause cuts and abrasions like corn chips or potato chips.
Sexually transmitted infections (STIs) other than HIV can be easily transmitted by cocksucking, due to bacteria being present in the cock or throat. It is very important to consider the number of cocksucking partners you have had in determining if you need a sexual health check. If you regularly have sex with lots of different guys then it’s a good idea to be checked every three months.
