I don't know why I get so sexually turned on by exposing my boyfriend naked to other girls. I've tricked him into getting caught a few times and he never complained about it. I think is watching the embarrassing expression on his face of being seen naked. I know he likes because his ends up getting an erection. Is this normal?? Do I need a shrink?? Or do other women do things like this?? I just know that it turns me on and makes sex that much better.
