Having Trouble Making My Boyfriends Cock Hard

I really does not know what is going on with my boyfriend, he used to be horny all the time and his cock was always rock hard, we used to fuck all the time and now he can not even get hard for me, sucking, moaning, touching, nothing helps! I know that he still loves me, maybe it is because all the cam whoring thing but he was the one to suggest it in a first place, I really don’t know, help anyone?
