Wow, I am surprised there are this many people here who are into it.
Trippin, role reversal is very common in Dom/Sub. IRL, I am a doormat, I let people walk all over me. But when I put on a uniform, I am no woman to mess with. I can be as powerful and strong as I want. I also have a fear of sex and have to be in control. I'm not comfortable with being dominated or controlled during sex. So it's pretty natural to be dominant IRL and submissive in the bedroom.
