Why the hand

Hey guys I have been having a problem with my man jacking off all the time. I bring it up and he denies it. I have walked in on him 2 times in the past. I just know he does it at least once a day in the bathroom, it makes me sick I’ll walk in in the morning and it will smell like cum and there will be a wad of tissue in the garbage. I am horny all the time and want sex! So it’s not that he isn’t getting any he doesn’t want it 🙄. I love him to death but idk what to do anymore we have been together 2 years, and he has never wanted to have sex much we argue about it all the time. I think he has a testosterone problem and have been working on getting him to go to the doctor but he is self conscious about it .Has anyone gone through the same problems? Had a dream that he was gay and it all made sense lol, but he definitely isn’t 🤣
