Logic dictates that if the condom was hanging part way outside of her vagina, then your penis HAD to either still be inside the condom.......or your penis came out of the condom AFTER you had withdrawn leaving part of the condom outside her vagina. Which means the head of your penis WAS either covered or completely outside the vagina which equals NO RISK.
Test if you want, but it will be for your peace of mind only.
If the condom was partially OUTSIDE the vagina, then either the head of your penis was still covered OR the condom had slipped off your penis AFTER you had withdrawn completely. Either way.......NO RISK.
If the head of your penis was covered, menstrual blood, along with any other fluids, would not be a risk.
If you are still having anxiety about what happened.........then go get tested for YOUR peace of mind. I can't give you a definitive assessment if you can't me a definitive risk.
As long as the head of your penis was still covered by the condom, you had NO RISK.
Blood on the outside of the condom was most likely an indication that the woman was on her period and is NOT an HIV concern.
Again, as long as the head of your penis was still covered, there is also no need to begin PEP.
Anybody who can help me with one? Thanks...
BTW, just to clarify. As she was on top of me, she moved up and I saw that the condom was hanging from her vagina with the real end (only maybe one centimeter) of my penis still in the it. It was not inside her or on the bed.
