Hi, About A Month Ago, Me And My Boyfriend Stopped

Hi, about a month ago, me and my boyfriend stopped having sex.
He would say he was to tired or he doesn't have a sex drive and I just couldn't get my head around it. Last night he did talk to me in detail about it and he said he doesn't enjoy sex, and it was the same with his past partners. He said its because he ejactulates to quickly and he doesn't have a chance to get into it but I miss having sex with him because it made me feel closer to him
