me and boyfriend have had sex when I have been having my period and it's fantastic, i always get randy as hell when i have my period and my current man is the only one who has actually had intercourse with me during a period. it can be painful sometimes but then we just have a bit of mutual masturbation, or i give him head. i've found that if you do it in the bath or shower it is sometime less painful, don't know why, might be the water??? never mind, doesn't matter, all i know is that we never have to let our sexual appetites go to waste!!!
