Is it normal that i'm like this? (dealing with sex/fetishism)

Okay, so first off, hello to everyone. Bear with me as this may be long, please. :)
I have a lot of fetishes, and yes they are all sexual. Sadism, masochism, villainy, blood, criminals (murderers only), cocky guys, being cocky, and a lot of other ones.
A few years back I was raped by an ex and it changed me almost completely. Could my fantasies/fetishes of power be because of that? I am NOT in any way condoning rape -- quite the opposite. I don't believe in people being raped in real life but I oft-times masturbate to being forced against my will *WITH SOMEONE I TRUST*.
I also fantasize about being forced to give my boyfriend oral sex. Lately he's been putting his hand on my head while I do, and secretly I wish he would make me gag. He did once, on accident and I thought it was SERIOUSLY hot.
Another thing I fantasize about is being kidnapped. It's a loss of power, I think. Loss of power drives me wild.
I have RP'ed before with the idea of my body being "used". I orgasm so hard when I do, and I think my bf loves it too. I adore dirty talk as well, and don't care what I'm called as long as it's strictly in the bedroom and not real life.
So, to sum up, my questions are:
Could my loss/gain of power fantasies stem from my rape?
Is this typical from a rape victim?
Thanks. :)
