I can relate to your problems. I have always struggled to maintain interest in my relationships. I am constantly looking at other women, fantasizing about having sex with them. I’ve been married for 4 years and I struggle to get motivated to have sex with my wife. 🙁
It sucks, especially for her and I feel bad about it. I’ve recently starting looking into, and trying to understand whether my ADD is the cause of my ‘always looking for the next / a new shiny thing, or whether there is something else going on in my head.
