My kink wrong and yours right?
Two girls 69'ing each other. It's a huge mens fantasy maybe even number one on the hit parade for a guy to have two women in bed with him and see them going 69 on each other. Most guys really get there rocks off just thinking about it. To see it actually happen, the guy is in paradise! He's just happy to look for an opening for him to join the party!
Face it, the guys are the ones saying no guys because they don't want the competition. The women who says she'd rather have a female than 2 males is usually bi or bi-curious herself. And nothing wrong with that but it's usually the male ego that won't let the other boys play with his toy girl.
