He tells me he masterbates to porn like 2-3 times a day. (Not a fan, but what can I do? We don't live together.) whenever we do anything sexual he never cums ever... We had sex for a hour and a half and he didn't... Gave him a bj for 2 hours (and I deep throat) and he didn't. (First guy this have ever happened to me with)  ut when we do stuff to porn he can... Has it rewired his brain or something or am I just not doing it right?
