Husband has lost his marbles?

Your culture is very different than how he is choosing to live, but for some cultures, this is all very normal. If you intend to continue in this marriage, if you care about him and want to make this work, then perhaps you should make an attempt to loosen up and try to enjoy some parts of this lifestyle with him. I'm not saying to do everything he's asking. Maybe you can find a compromise. If he wants so much more than you do, then, you should let him know that it's ok for him to masturbate sometimes. If he would stay away from the adult movies, and things that are arousing him, then, he may not have the desire for so often. If you are trapped in this marriage, then, you're going to have to find a way to deal with it. I don't know what country you are in, but sometimes, it's better to leave these situations and deal with those consequences.
