Jealousy

Am I the only one that gets jealous and insecure when we're watching tv or a movie and another woman has her boobs out or showing more than needs be or they're doing a sex scene. I get really uncomfortable and can't stand sitting there thinking what is he looking at? How am I meant to be comfortable with my own body when models/actresses are showing way too much unnecessarily!! All these movies about college and especially the American pie movies are so awful to me I can't stand it. If he watched porn that to me is a form of cheating because he is watching another woman being intimate and touching himself. Does anyone else feel this way? Please no comments about how we should love ourselves and women who love their body shouldn't be put down for wanting to show it I know all that. I just get so upset I end up crying on my own somewhere.
