Is it normal to want to have sex with your mother?
Don't bother with the Christian remarks, or just simply "eww" if you don't agree. If you're going to comment, leave a real comment.
I have had a thing for my mother for years. I know normally it's a childhood thing, but I'm a legal adult now, and my mother is single and alone. I still find it sexually exciting to want to have sex with her. It's not romantic, it's not physical attraction, it's just sexual.
