to caradecanoas :Exactly! Some of us are born with this mysterious need to be inseminated and to feel our insides filled by a virile member, even though emotionally we may prefer women. The pain that we may eventually feel is nothing compared to the pleasure of feeling this mysterious void within us being filled.
It may hurt a little, but is an incredible sensation. It messes with your brain chemistry. When your man finishes his job and gives you his sperm, you'll feel a strange happiness, a "mission accomplished" sensation. You, the bottom, don't even need to cum to feel that.
