To be honest, the thought never occured to me that I could have sex while menstrating. It was just the time of the month when we took a break. Then I read an erotic romance, a paranormal one, the heroine was freaked that he could "smell" how bad she was and wouldn't let him in the house! What followed was probably one of the most romantic love scenes I've ever read! It is on our list of "Things to try at least once."
