What Risk and Time for PEP ??

[WhatToDo??]

This is what happened to me. About 36 hours ago, I had a wet massage with a CSW. I was on my back and she was on top, sitting and slidding on top of me.  I was getting very aroused and I'm sure there was lots of pre-cum (from me and maybe from her as well), plus water and soap, all around.  While I'm not completely sure there is a (good) chance that I penetrated her.  I was not wearing a condom cos I did not expect things to turn that way When I realized what could have happened, maybe 5 mins  had passed, and I stopped right away.  What's my risk of HIV (assuming she was positive)?  Should I go for a PEP? Even if the risk is small, isn't it better to be safe?

What,

You certainly do not need PEP. For a start, you aren't even sure if you penetrated her. PEP is a heavy-duty combo of drugs that are not to be taken lightly.

Hiv is a fragile, difficult to transmit virus and more so from a woman to a man. Even if she is hiv positive and even if you did briefly penetrate her, you are highly unlikely to end up hiv positive over this.

I really rather doubt that you would have penetrated her without either of you noticing. And simply rubbing genitals together without penetration is called "frottage" and frottage is not a risk for hiv infection.

If you continue to have doubts as to whether or not you penetrated her, get tested at the three month point for peace of mind. As a sexually active adult you should be getting tested regularly anyway.

Here's what you need to know in order to remain hiv negative:

You need to be using condoms for anal or vaginal intercourse, every time, no exceptions until such time as you are in a securely monogamous relationship where you have both tested for ALL sexually transmitted infections together.

To agree to have unprotected intercourse is to consent to the possibility of being infected with an STI. Sex without a condom lasts only a matter of minutes, but hiv is forever.

Have a look through the condom and lube links in my signature line so you can use condoms with confidence.

Anyone who is sexually active should be having a full sexual health care check-up, including but not limited to hiv testing, at least once a year and more often if unprotected intercourse occurs.

If you aren't already having regular, routine check-ups, now is the time to start. As long as you make sure condoms are being used for intercourse, you can fully expect your routine hiv tests to return with negative results.

Don't forget to always get checked for all the other sexually transmitted infections as well, because they are MUCH easier to transmit than hiv.

Use condoms for anal or vaginal intercourse, correctly and consistently, and you will avoid hiv infection. It really is that simple!

Thanks, Ann. 
Just to be sure I understand how to weigh the risks.  If I did not penetrate, then there is absolutely no risk (even if the CSW is positive).  If I did penetrate, there is a small risk depending on whether she is positive, and degree and length of penetration. That I am male reduces the risk further.  Is that right?  Since I don't know many of these factors, shouldn't I just take the PEP.  A very small risk is still to be eliminated.  Why not? Grateful for your thoughts.
