<human>: Summarize the given text in a few sentences.

Long story short, my BF can't keep it hard. At the start of our relationship we agreed he would cut back on masturbating to help with his ED.

I'm a good sport, so I will find a way to make us both come when he can't keep it hard, but it's much less satisfying for me, so it's important to Me that he doesn't masturbate much, if at all. Every now and then I check in on him to see how much he's been masturbating (there's been little to no improvement in his ED), and to my surprise he always tells me he hasn't been jerking off at all. 

A few months ago, I caught him doing it in the shower to anime porn (which he specifically told me he didn't like...?). Dinner was getting cold so I came in to playfully tell him to hurry up, and there he was. We had a little tiff over it, as he knows his ED is an ongoing problem and had promised to not jerk it, but he said it was just the once, so nbd.

Now, last night we're having sex. He's soft as usual, but I'm a champ so I'm not acting like anything is wrong. I go to blow him and he tastes strange. Hm. When I go to the bathroom after sex, I check the closet and sure enough he's gotten into the massage oil/lube I bought us as a present. 

When I come back, I ask him if he had masturbated recently and he straight up tells me no. I have yet to confront him, but I admittedly feel betrayed. I feel like these are no longer one offs. I've suspected a masturbation addiction for a while, but he always promises me he rarely watches porn or masturbates. Since he lied right to my face, I don't really know what to think.

Any advice reddit?
