Jealousy is related to insecurity and both have roots in fear. What do you fear by this behavior? I know that my fear in this behavior stems from may by bf will think someone is prettier than me or think about another girl while he's with me. My current bf doesn't do this, but in the past I've just kinda tapped my bf on the shoulder, laid a sexy kiss on him, and whispered as seductively as I could,"I'm the one you're going to bed with tonight." Then turned and walked away. After a few times of that happening, the behavior stopped.
