well no, but my bf and I were messing around while I was on my period, like fingering...but it was good, we just cleaned up afterwards.
It's really no big deal. If by "while you're having sex" you mean in the process of intercourse, it casn happen. Deep penetration and contractions (like from her orgasm) can start her period if she'd on teh verge anyway. If it's a surprise, it can be a little messy and call for buying a new set of sheets. If it's expected or she'd already having her period be prepared ahead of time. Some women like sex duriong their period, some don't, sme say it's even better. I'm cool with it eitehr way, I'll even go down during it, you'd be surprised how hot a women will get if you slooooowly, teasingly pull her tampon out with your teeth while licking her. Finally having said all that his is blood we're talking about and it is DEFINITLY NOT SAFE SEX. if you're going to play during her period it's best to do it with someone you're in a committed relationship with!
If your worried about the mess, have her be on the bottom, its cleanerthat way, or the shower works too...good luck
Having sex with a woman is gross to start with, and it just gets worse the longer you're with one.
