Home alone and aroused: Watching porn and pleasure myself on the sofa

I'm not sure about what's happening with my wife. She seems to be acting weird lately and I think that something is going on between us. We are having some problems in our relationship and I don't know how to solve them. But when I'm alone at home, I can't help but get turned on by the thought of her. So, I like to watch some porn to get myself aroused and then pleasure myself on the sofa. I don't mind watching some softcore stuff, as long as it gets me excited. Sometimes, I even fantasize about my wife getting down and dirty with someone else while I'm watching. It's not like I'm into that kind of thing, but I can't help myself when I'm alone at home. I like to play with my pussy and stroke my big tits while I'm watching some hot videos on my computer.
