Recently I visited a massage parlour in India Mumbai. After the massage The female therapist gave me a blow job,she used a lot of her saliva for lubrication and we also kissed deeply with our mouths . The oral was atleast for 10-15 minutes also during the act she removed her Inner wear and I think we both had our genitals touched or rubbed for a minute or 2 minutes. They was no vaginal sex involved except for fingering. She finished me by handjob. Acts performed are 

From her Oral to my penis( blowjob)using saliva as lubricant,  French kissing, body rubbing, fingering and touching or rubbing of both our genitals. 

So doc my questions are

1.Is there a chance of HIV from above act?( I am most worried about hiv)

2. Is there any chance of Sti like herpes?( they were no visible lesions on her mouth or vagina area)

3. Chance of any other sti from the above act?

4. Should I take prep to be on safer side?

The blowjob was for 10-15 minutes without condom, her saliva was used for lubricant. Kissing on the balls, body rubbing and lips kissing. No visible sores on any Part of her body. What’s the possibility of HIV/STD transmission to me if she has any of the infection active ?

Thank you

You describe a sexual exposure that had little or no chance of transmitting any STI and absolutely zero risk for HIV. Saliva rarely transmits STIs and probably never HIV. You did not have penetrating sex of any kind (except fingering, but that's zero risk). Those comments pretty well cover your four questions, but to be explicit:

1. This was a zero risk exposure for HIV.

2,3. In theory, HSV, syphilis and HPV can be transmitted by genital rubbing and other non penetrating sexual practices. However, all these are very rare in situations like yours. I have never seen new herpes or syphilis in a patient with exposures like yours. The chance for both surely is under one chance in thousands. The possibility of HPV may be slightly higher because HPV is so common. However, everybody gets genital HPV somewhere along the line; as a sexually active person you can assume you already have had HPV; and this single event does not significantly increase that likelihood.

4) PEP to prevent HIV is not something I would advise in this situation. I wouldn't even suggest testing for HIV (or any other STI) after such an event. However, you are free to seek testing if the negative results would further reassure you -- such as HIV and syphilis blood tests after about 6 weeks.

I hope this information is helpful. Let me know if anything isn't clear.

Your risk of HIV was very low and possibly zero:  there has never been a proved case of HIV transmitted oral to genital. On the basis of how HIV infected people thought they were infected (which often is mistaken), years ago CDC calculated a risk of one chance in 20,000 if the oral partner has HIV. That's equivalent to receiving BJs by infected persons once daily for 55 years before infection might be likely. The risks of syphilis, gonorrhea and herpes are higher but still very low. You could consider having a throat swab test for gonorrhea (valid any time more than 4-5 days after exposure) and, as suggested above, syphilis and HIV blood tests in a few weeks. Blood tests for herpes are not recommended; the tests just aren't that good and the results often unreliable.
