I'm from tel aviv israel, 37 male, married. In the past i had a lot of sex with csw and regular girls outside my marriage until i was started to develop guilt and fear about hiv,  i desided to stop this behaviour,  got tested for hiv and other STDs all come back negative (i always used condoms). Since then i  practice only what i was think was safe sex. Massages, handjobs and some times oral (been sucked). Today i tried something new and i'm worried that it was risk activity. I went to woman who gives bdsm services. She told me she isn't make sex with clients at all. She sit on my face and i licked her anus for something like 15 minutes, and maybe her vagina to (not sure about it), It was intensive. I don't have sores or any visible blood in my mouth. She also gave me oral without condom.

After this i felt very guilt, and again all those worries like in the past come back. 

Do you think it was risk activity for hiv?

Do you see medical reason to test for hiv?

Is it safe to make sex with my wife?

Now im understand that i need to stop with all the sex acts outside my marriage, it's probably not for me. Hope its not to late.

Thanks alot. 

Welcome to our Forum and thanks for your question.  I'll be glad to comment.  Congratulations on your decisions to practice safe sex.  In all probability, your partner does not have HIV - most CSWs to not and since she does not have sex with her clients, it is unlikely she is infected.  Even if she was, the events you describe above are very low risk for HIV.    To provide more detail:

She told me she isn't do sex with clients, but I'm not sure about it. 

If i was know for sure she is hiv+ do you still give me the same recommendations?

Still no need test? It's just a question, im not really know her status. But im try to refer partners of unknown status as hiv+ just from safety standpoint

This is my last thread.

Can you please try to explain to me what is the meaning of very low risk? 

Is it only theoretical? 

Im worried because when i licked her anus she sit on my face and it was kind of choke so no air was involved, is it not enough good environment for the virus to pass through her anus/vagina to my mouth?

Thanks, hope my questions not sound stupid. Im hope i will never do this again. 

My mind can't stop thinking - what's if...

In science nothing is 100% because we learn new things every day.  Thus "very low risk" is essentially zero.  Your risk of being struck by a meteorite today is very low and about the same magnitude as your very low risk of getting HIV from the encounter you have described.  I know of no evidence that analingus has ever lead to acquisition of HIV.  

I hope you can stop worrying. There is no scientific reason for worry.

As you point out, this is my 3rd response and thus this thread will be closed shortly.  I hope my comments and the information I have provided has been helpful.  EWH
