Last night I went out drinking with a buddy of mine. One thing led to another and I went to a massage parlor. 

I remember her putting on the condom using her mouth. However I have some skin bridges and sometimes, it makes it a little more difficult to get the condom on. It’s a little difficult for me to remember clearly whether she got it on properly at first. But, if she didn’t do it correctly, her mouth would have touched my penis briefly. 

Following that we had sex, missionary. Not to be graphic but a few times, I put my pelvis firm and flush against he vagina. Condom came out in tact. 

My apologies if this is graphic, being that I have skin bridges my head is not completely uncovered by my foreskin. When I pulled it back this morning it was moist (this normally happens after raw sex or raw blowjob)  or maybe there is something in the condom? (It’s been a LONG LONG time since I’ve used a condom). 

What are the risks of STD? I would assume fluid transmitted diseases are basically zero. What’s about everything else? 

Being that she might have given me a very brief, maybe 30 second bare back blow job enough to transmit something?  I couldn’t really see her mouth when she took her mask off, it was dark. 

The chance you acquired HIV is zero for all practical purposes. First, it is unlikely any particular massage parlor sex worker has HIV -- in most cities and countries, well under 1% chance. Second, oral sex is zero risk even without a condom. Third, even with entirely unprotected vaginal sex, the average transmission rate from an infected female to her male partner is 1 chance in 2,500.  With a condom that becomes zero risk for all practical purposes. The details of condom use you describe don't matter:  it seems clear the head of your penis and your urethra were covered while in her vagina. So your HIV risk is zero.

Other STDs? Maybe somewhat higher risk. HPV is possible -- but everyone has or gets genital HPV, and this event doesn't elevate your risk any more than it was anyway. Herpes, gonorrhea, chlamydia, syphilis? Extremely low risk -- low enough that testing is optional.

In general, STD/HIV testing isn't necessary after any single exposure like this. Instead, a smarter approach is to not worry about individual exposures, but to have routine testing from time to time, like once a year. However, if you remain concerned about this particular exposure, I would suggest a urine gonorrhea/chlamydia test, which is valid any time more than 4-5 days after exposure; and blood tests for HIV and syphilis after 6 weeks. In the meantime, try not to worry: the odds you have any of these is extrremlye low.

I hope these comments are helpful. Let me know if anything isn't clear.
