There have been a few times when I fucked a girlfriend when her period had JUST ended (or so she said), and it was enough to bring back the blood for another day or so.
I remember the first time I fucked a girl on her period, a week or 2 after I had sex for the first time. Her ass was covered in blood, my cock and hands were all bloody, part of my stomach and upper legs had blood all over, and let's not even talk about what she did to the bed.
It didn't gross me out, but it was different!
To answer the original question, I'd think that if she has any bodily fluid transmitted diseases, then it'd be in her blood during sex too. Otherwise it's not a big deal. |
