Should I believe him?

I write a lot, but the reason I write a lot is because I know it's virtually impossible to fully explain a situation to strangers on the internet.
Even with reading all of my posts, there's so much content and detail you don't know, unless you literally want me to write a book on it.

What I'm saying is that I'm coming to these forums for help with my problems, so of course I'm going to write about the problems. What I'm also saying is that at the moment, there are plenty of other variables that make me want to stay in this relationship and continue trying. What I'm saying is that there are things that still give me hope, such as him being willing to work on problems and change behaviors and attitudes.

So yes, I do get frustrated when someone comes in and assumes that all hope is lost and that I should just count my losses and move on.
In this situation, I fully believe that leaving would be the lazy thing to do.

I do not think we, on the internet can tell you what you "should" do in your relationship. I think the comment about what all men do was masturbate, not necessarily watch porn. How they masturbate is individual, I suppose, like how I do versus how you might.

I have been married for 25 years now and my husband watches porn occasionally and I helped him sell his old Playboys on the Internet back in the 1990s, some issues were worth $80 apiece. We both laughed when I had made over $350 and he commented, "Well, I guess I can afford to renew my subscription?" (it was something like $60/year back then).

I do not think my husband's sexual preferences are about me. He chose me initially partially because he found me sexually attractive. Good thing that is not the totality of our relationship as we each have gained over 100 pounds in that 25 years and he's bald, to boot! In my experience sexual interests and attractions come and go for both men and women. When he looks at a good looking woman walking by, I generally am in there with him commenting on her looks/sexual appeal. That is not to say I am bisexual, but an attractive woman is an attractive woman but that does not threaten me and my attractiveness to my husband or our relationship.

Other people are not part of my relationship with my husband. I would believe your boyfriend; I do not really see any other alternative? If he is lying, he is lying. Eventually you will know that to your satisfaction (in the sense of not having to guess whether he is or not). I do not think you can change this man so he likes/believes/acts like you would like him to.
