EJackson, I was married to a guy that had the same problem.
I know that when you first know he is doing it, you don't really realize the full extent of it. Later I found out that he had whole collections of CD's that he had downloaded from the net. He stored them in his computer room and he felt that he had possession of the women in those films.
In other words he was collecting intimate times with these women. I looked at one of them when he was not home and it was disgusting. He was a paying member of many sites including live web-cam sites, he was on his computer as much as 6 hrs a day. It's a sickness and you need to save yourself. I know what this is doing to your self-worth, you must get out and if you still want another man after this, find one to whom you are the most important thing in his life.
Needless to say I am divorced. send me a PM if you want.
