I've discovered another reason why I don't sleep around.
I like the whole cuddle, hold, etc... thing after sex. Corny, I'm sure, but I do like it.
I look at it this way. There's a girl that I could sleep with right now if I wanted to. And when I'm horny, I'd want to... but... after it's over, since I don't have feelings for her, I'd want to just grab my shit and go. And I don't want to hurt a girl like that. But, the girls that don't mind me doing that are the slutty ones and I don't that.
And that's just on top of the morality aspect.
