Welcome to the Forum. Your question is a good one and one for which there is little formally collected data however that practical fact is that if, following sex, a condom comes off as you are removing yourself from a partner, the condom has done its job, staying between you and your partner. thus unless you develop symptoms, I would not be concerned. After all, remember:
1. Most people do not have STDs.
2. Most UNPROTECTED exposures to a partner do not result in infection.
3. You used a condom which was between you and your partner's mucosal surfaces for the duration of your intercourse.
Is there any certain guarantee to this? No but the fact is there is very, very little risk. I would not worry if I were you. I hope my comments are helpful to you. EWH
This is certainly far closer to protected sex than not. EWH
Dr. Hook,
Thank you very much for your informative answer and prompt reply. Just one last question, I know that you said there is little data on condom slippage like I experienced, but for all practical purposes would you say that this would be considered protected sex? Just curious to know where my encounter lies between unprotected sex and safe sex.
Your forum is a great help. Thanks again.
