Is it me?

My S/O masterbates daily. Sometimes multiple times a day. I’ve caught him sometimes and other times he doesn’t know I know he is, little things he does and behaviors let me know when exactly he is, plus he only does it in the bathroom. But the problem is, he’s masterbating daily and we only have sex once a week or longer. He knows I have a high sex drive, he knows I need and want the intimacy more often than receiving. He tells me he does it because it’s quick and can get it done faster solo and sometimes I’m sleep, he’s also said that he just doesn’t have the mood to have sex all the time. I get it but if you don’t want to have sex all the time how can you watch other people have sex(porn) and jack off, while I’m sitting in the other room? He also says that sometimes me being all over him all the time kinda turns him off because he doesn’t like people touching him all the time, so I stopped being so overbearing with touching him, but he still isn’t touching me or showing me any sexual attention except that 1 day a week, and even then my needs aren’t met.... is it me? Is he masterbating more and having sex less because he’s not attracted to me?
