I'm a male and I received yesterday a blowjob (without condom) from a women during one minute or so.
She told me that she had dental surgery (wisdom tooth removal) less than 48h back! She was not bleeding but obviously the wound was not healed yet.
Do you beleive I can catch HIV from that situation?
Many thanks

Welcome to the forum. Thanks for your question.

Oral sex is safe sex in regard to HIV. There has never been a proved case of HIV transmission mouth to penis. Some people believe that's how they caught HIV, but in just about every case investigation found they were not being truthful or had had other exposures they didn't recognize at the time. CDC estimates the chance of transmission, if the oral partner has HIV, at once for every 20,000 exposures. That's equivalent to receiving oral sex by infected partners once a day for 55 years before transmission might be likely.

Further, HIV remains uncommon in women in the US. Statistically there is under one chance in a thousand your partner had HIV; even if she is a sex worker, there's still under 1% chance (1 in a hundred). Finally, having had recent dental surgery doesn't really make much difference. Various conditons with blood in the mouth (dental work, inflamed gums, biting the tongue or inside of the cheek) are very common events, so there must have been billions of oral sex events in the presence of small amounts of blood in the mouth -- and still no known HIV transmission. Finally, on top of all that, saliva kills HIV -- which is one reason oral exposure in general (e.g. kissing, oral sex) carries little or no HIV risk.

So I truly would not be worried at all about HIV in this situation. I do not recommend preventive treatment or even HIV testing. If you have a regular partner you can safely continue your normal sexual relations with that person.

You were at greater risk for STDs other than HIV, especially gonorrhea, herpes due to HSV1 (if your partner has oral herpes), and nongonococcal urethritits (NGU). However, all of these are likely to cause symptoms you would notice. If you do not develop discharge from the penis, painful urination, or penile sores within 10 days, you probably didn't catch any of these. For earlier reassurance, you could consider visiting a doctor or clinic for exam and testing.

I hope this information has been helpful Best wishes and stay safe--  HHH, MD
