Ok, here's my argument against your lesbian activity.

The following body parts make me very happy:

Boobies!
buttocks
clitors/vagina/p word

Females are the beholders of such anatomy gifts. By you not wanting males, I often feel saddened and am forced to have admiration, but with pointless pursuit. You don't want me, but I want you. This creates a permanant form of torture, commonly known as blue balls.
