Welcome to the Forum. I'll be pleased to comment on this exposure. Despite the fact that your partners may be at relatively high risk for HIV and other STIs becasue of their lifestyle choices it is unlikely that they were infected and the activities you describe did not put you at risk for HIV. There are no proven cases of HIV which have been acquired as the result of receipt of oral sex. You are not going to be the fiurst and should not worry, nor is there a medical reason for you to seek testing for HIV.
There are a few other STIs which might be acquired through receipt of oral sex but the risk fo them is also quite low. Most common is nongonococccal urethritis or gonorrhea however now, five days after the exposure you likely would have developed symptoms of urethritis (burning on urination or a penile discharge) by now if you had been infected. There there is also a (mostly) theoretical risk for syphilis or herpes however if your partner did not have sores on her mouth, there is little risk for these infections. Unless you develop a visible sore or sores on your penis in the next few weeks (you could develop herpes lesions for up to two weeks after the exposure, syphilis lesions could potentially develop as long as three to four weeks after exposure), I really would not worry and see no need for testing.
Bottom line, this was not a particualrly high risk exposure, In the absence of signs or symptoms I would not worry. If you need the peace of mind provided by negative tests, the most important tests would be tests for gonorrhea and NGU which should be readily available from your own doctor or at your local health department.
I hope this comment is helpful. EWH
Thank you Doctor. Just one more before I let you go.
So I can have protected vaginal sex and unprotected oral sex with my gf with probably no transmission?
And the herpes risk is it HSV-1 or HSV-2 or both with oral sex? Hsv-1 is the one most people have right in their mouths?
Thank you.
I would not worry about unprotected sex with your GF if I were you.
The risk for HSV from oral sex is for HSV-1, the virus that the majority of adults have as oral infections. HSV-2 infections from recipt of oral sex is exceedingly rare.
Take care. EWH
Doc if I may,
Yesterday overnight I developed a sore inside my mouth, it was mostly painful when i woke up sleeping. It was inside of my lip and I could not see the actual sore. I had the sexual encounter on the 15th of December. On the 21st I had unprotected oral sex with my gf and kissed her later on. I got the sore on the 27th of December. Now to me the timing does add up. Is it possible I got herpes on my penis from the 15th then gave it to my girlfriend on the 21st and got it on my mouth from kissing her then gotten a sore on the 27th? On the 15th encounter we did not kiss and I washed my hands and doused my hands in rubbing alcohol. I am not quite sure but I have had like acne pimples occur near my lips and some sort of sores on the inside of my mouth before (probably canker sores). Today the sore whatever it is is more visible and its red. Its not too prominent but its there and not too painful. So bottom line could it be herpes?
Herpes is not spread without direct contact. Thus, if the sore on you mouth/lip is HSV, you got it from your former GF, not your encounter on the 15th. Alternatively, this could be a a recurrence of oral HSV that you already had or a non-STI canker sore. To rule out (or in) HSV you need either a PCR or culture test taken from the lesion and sooner is better than later. EWH
