This is for guys who are sexually active Just something I'm curious about... When you are having sex and the woman is on top - do you squeeze your PC muscles alot more than you do in other positions? I noticed I squeeze my PC muscles alot when my girl is on top of me for some reason... I also do it alot when I'm behind her.. and I stay still and let her rock back and forth on me. In regular doggystyle I don't squeeze them much, however. Do any of you guys do anything similar or no?
