Worried his high sex drive is bringing mine down

So long story short my boyfriend (M24) and I (F22) have been dating for about 10 months, started dating in February.He has always had an extremely high sex drive and could literally have sex with me all day every day if he could. When we first met we had sex every day multiple times a day. (We also didn’t have jobs at the time so we were home all the time.) anyway, I didn’t mind having sex so often because I’m completely infatuated with him and we have amazing chemistry in and out of bed. But as our relationship progressed, certain instances of infidelity happened on his part (I found many dating sites and a secret Snapchat, this was going on from about April-August) a lot happened in between that time frame that’s too long to explain but I forgave him and we both decided to keep working hard towards bettering ourselves and the relationship. While all that crap was going on I found out about a deeper underlying sexual or porn addiction that he has. Once he realized how much it was affecting me and the relationship he began this no fap thing but hasn’t been really fully committing.

Since all that stuff happened my self esteem and sex drive have decreased by a lot. We have regular sex, at least 3-4 times a week, sometimes more. I’ve even lasted 7 rounds -_- I tell him we do it a LOT more than regular couples but he still wants more. Even if we go a day or two he still sometimes gives in and watches porn. This hurts me because I don’t want the addiction to take over again and eventually hurt us even more. there’s even times when we would go without sex for like 4 days and he gets extremely irrational and pissy and blames his behavior on me not giving him enough sex. Every time he tries to initiate sex and I don’t want to, he gets sad and it makes me feel like crap. Sex is starting to feel like a chore and all I think about is that I’m not satisfying him. the more that I have to actually think about having sex the more I don’t want to do it. I’ve even tried to talk to him about how to raise my libido so I can match him but I feel like that’s impossible since he’s so horny ALL THE TIME.

I don’t really know what to do and I’m worried that our sex life is gonna suffer. I just wish he would understand that I need a day or two off sometimes and that he would just wait for me and not make me feel bad that I’m not satisfying him enough.

Edit/clarify: he never slept with anyone else or tried to meet up with anyone. He just used those sites to get off.
