My boyfriend masturbates a lot. advice?

So , we aren't actively ttc , but we are letting nature do what it does. We don't have sex as much since he works , but when we do, we do 😂. Last night we did 2 rounds back to back then he went home. Supposedly he woke up with pain, this happens to him even when we don't have sex, then he told me that he jerked off after he got home. I don't see why he had to, we went 2 rounds, after he left I literally had the best sleep ever, but supposedly he said he needed to so he can sleep. He says he thinks of me but still, I think it's an addiction because he does this all the time, jerks off more probably 2 times a day. Or is that like a normal thing for a guy? I haven't masturbated since I became intimate with him. 🤦🏻‍♀️🤦🏻‍♀️ idk what to think honestly
