I am talking about Sexual intercourse, not foreplay, the actual act of sexual intercourse. The thing that seperates a woman from a man is the fact that she has a vagina, if you have those two options and prefer to use her ass then in my opinion you are a bisexual in denial of the truth, your dick cannot tell the diffrence between male and female guys.
Dosen't the thought that your putting your dick/tongue where shit comes from put you off at all?
