For the first time yesterday, I was fucking my girlfriend's brains out, and my nose started bleeding everywhere. So I stop thrusting and realize there's blood all over the place and I'm like fuck this sucks. So we stop, wait a little while, and get back to fucking. Sure enough my nose starts bleeding again. So we stop, wait a little while, and get back to fucking. Sure enough my nose starts bleeding again. Now after the third time I was getting mad that my bleeding nose was preventing me from having fantastic intercourse.
So I look that shit up on the internet and it means I've got high blood pressure, and that I can have a heart attack during sex at anytime if I'm not careful and don't start taking some gay medication.
Anyway, the problem was eventually solved by her just riding my dick like never before.
