Sex is for the babies. If by the end of the night, the girl in my bed isn't pregnant, I did perform my God-given duty as a man.
Just kidding. Sex neeeds not a purpose. It IS the purpose. Why did you do anything with anyone today? Because if you sat in your house and fapped all day to porn, you wouldn't get sex. On the other hand, if all you did today was stay at your house and fap, then the reason you did so was to deceive your penis who is doing its best to get you the sex you need and deserve. And lastly, if all you did today was stay at your house and fap, but you do not have a penis, please IM me, because we have much to discuss.
