I went to massage and got a condomless hand job and put my ungloved finger into the vagina and stroked clitoris of the csw(who from Brazil,  this took place in UK) . No oral, sexual intercourse, gential to gential contact took place. 

Are there risks of any stds such as chlamydia, hiv, syphilis etc if  around 8 mins after fingering  I touched the head of my  penis where it is likely some vaginal fluid was on my finger at the time. This was after I rinsed my hand with warm unsoapy water. 

2. Due to anxiety I have been on HIV Pep for this for for around two weeks (raltegravir and emtricitabine/tenofovir-df) How long does this take to surpress any viral load? I had unprotected sex with my female partner a week after this event. 

3. Is there any chance of infection if I had a small cut on penis  and she had a cut on her hand? Or if I had any cuts on my finger during the fingering. I ask as I have been having symptoms such as fever, tiredness, chills and headache (but could be due to PEP) 

Before I get into specifics, let me say that the encounter you describe is considered to be a no risk exposure for acquisition of HIV and other STI‘s. The activities you describe, include both receipt of masturbation and masturbation of your partner, both of which are considered to be no risk exposures by the World Health Organization and the US CDC.  There is no evidence that STI‘s, including HIV are transmitted from person to person through the transfer of genital secretions from one persons genitals to another on hands or fingers. Most experts would tell you that there is no need for treatment or even testing related to these exposures and certainly no need to take HIV PEP. Regarding your specific questions:

1.  See above. The contacts you describe are not associated with risk for STI‘s including HIV.

2.  HIV post exposure prophylaxis does not suppress the virus, but instead prevents infection from occurring. In all probability, most of this effect is accomplished within a few days of starting to take the drug however, convention is that HIV PEP should be taken for a total of 30 days for optimal affect.

3. The presence of cuts or abrasions, either on your penis or on your partner’s hands do not change the no risk nature of this exposure. 

I hope this information is helpful to you. I certainly no reason for concern about possible STIs, including HIV and no need for testing. EWH.

A quick foklow up, does it make a difference if I am HPV positive? 

And secondly should I then stop my Pep given no sexual intercourse took place 

Thanks 

You did not need PEP.  You can certainly stop it at this time.  EWH
