Am I a pervert?

I really am into hentai, I have a thing for BDSM(i think i am a sadist), I really love boobs. I know it's weird. That's why, I am writing this as anonymous, I had a crush on my best friend's mother when I was in elementary( its stayed till last year of middle school). She was beautiful, believe me! I think I had a crush on my bestfriend as well (she was beautiful as well). Its messed up, I know! But, seeing normal porn doesn't get me horny. Lesbian BDSM does! What's wrong with me?!.
