Why I’m a cum slut

My therapist says that my stepdad is the reason I’m a submissive cum slut. I’ve always thought im a slut because I crave being bent over and pegged but my counselor thinks that my stepdad coming into my life after nine years of just my mom and I and the fact he started whipping me the first day and still does In a humiliating way that I have programmed my mind to enjoy my stepdads beatings sexually and it’s made me crave dominant men. Does -anyone think he is right?
