Relationship in bedroom

Me and my boyfriend have been together for 2 years and have a newborn son, every since we got together he always expects me to go down on him and won’t do the same, he claims he doesn’t like to that’s it’s not his thing and sometimes I just want to stop pleasing him because I feel he’s being selfish, In the bedroom once he’s finish that’s it I’m left hanging dry no foreplay nothing he just wants to reach climax and call it a night, there are times where I think of other people but I don’t feel comfortable with cheating and I think I’m wrong for wanting more, he can’t please me sexually but expect me to do it for him and I feel selfish whenever I think about myself sometimes I’m unhappy it’s not all about sex but we’ve been together for 2 years and he only thinks about himself in the bedroom Am I wrong ?
