Dear Clara,
I recommend massive doses of selflove, self-appreciation, and self-re-evaluation. You must stop comparing yourself to photos of models and obsessing over all of your physical flaws. Get a grip. Instead of listing all of your bodies imperfections, start counting your blessings.
He looks because the images gives him some visual variety for his private fantasies. When we become jealous of pictures of naked women, it's like saying, "I want to own all of your sexual thoughts and control your visual images. I am the only woman you can think about in your mind or see in your imagination" - the ultimate fascist's demand.
Get my book "Orgasms for Two" and read the chapter where I discuss my own process of dealing with jealousy. It is similar to when I stopped smoking nicotine or letting go of any other addiction. Every time the feeling came up I simply said, "I don't do jealousy anymore" just like I would say, I no longer smoke cigarettes. I'm not saying it's easy but it's do-able.
Basically what causes jealousy is our fear of losing the person we love. Instead of allowing myself to go into the full blown feeling of an imagined loss of his love, I would distract myself by masturbating with a fantasy about having sex with some very attractive man who could fulfill all my dreams. "After all," I reasoned, "lovers can run off and they can get sick and die. Nothing is forever." Once I could imagine my life continuing past loving this one person, I could begin to operate from sexual abundance instead of desperation and deprivation. Enjoy yourself and your husband. Jealousy eventually drives people apart.
