Sex during your period?

[rouge-reverie.livejournal.com]

I was wondering if it hurts to have sex during your period? There is a possibility that I was going to have sex tomorrow, but it looks as though Aunt Flo will be visiting...I have heard that some women don't mind (even though I think it would be pretty messy...). The boy is pretty well endowed, so I'm wondering if wearing a tampon would be a bad idea. Is it better to do this in the shower? Help me out. Thanks.
