You don't act on your fantasies so I don't think you're a fraud..
Rape is wrong. But bdsm and getting physical really isn't wrong, just taboo.
Everything sorta is what it is.. Society then puts the label "good" or "bad"..
Some people like being dominated so my opinion is you gotta find those people and role play and just not take it too far. (:
There is a happy medium. I think sexual oppression can make the intrusive thoughts louder.
Just my opinion of course..
