OHMYGOD. I am so mortified. I was having sex with my friend earlier today and I thought I was no longer on my period, so I was all for it, right? He starts fingering me and then we start having sex and then he gets up for a second to re-adjust and he was like, "Shit!" and I asked him what was wrong and there I saw it... I fucking bled all over his goddamn bed! Argh, I think he kick started my period. Man, it was horrible. Can anyone relate?
