of course she can . she can have sex to .
It is normal to feel like you want to have sex on your period. A woman's hormones are going wild when on their period.
have you seen the csi episode... where a large woman killed a man during sex?
Sometimes. But see your doctor to be sure.
It is not only normal, it is refreshingly healthy.

Of course.
