What turns people into Freaks, etc.

[ImAlittleCurious]

Let me see if I can rewrite this.

Each person is different. Especially when it comes to sex. One person may like this the other is highly against it. May it be Anal. Swallowing, etc.

My girlfriend has swallowed me. She allows me to lick her anus. And at rare moments even willing to let me.. Well

She enjoys doing me. Fingering. Strap-On. Licking. Etc.

What I am trying to come across is. What makes one willing to do things like this? Is it due to sexual experience? Or maybe do too, what had happened to her as a child. (I do know somethings happened to her during then).
