Followup to boyfriend and lack of intimacy

He told me that the baby isn't an issue and that there's a difference between him being horny and us being intimate. He said when he's horny that he would rather masturbate and when he feels intimate with me thats when he wants to show me he wants something deeper. Is that a thing with guys? Or couples when they're in a relationship? It just bothers me cause we haven't had sex in the last three weeks and when I asked him how many times he has masturbated since then he said around 6 times. I lived with someone for a year and the whole time we were having sex atleast 3 times a day, but towards the end it got to the point where it became unhealthy and we just couldn't orgasm anymore even though we were in the mood, it had a part in destroying our relationship. I don't want to repeat that but at the same time once or twice every two weeks isn't making me happy. I told my partner I wanted to change that and asked what he preferred and he said that he likes it the way it is and that if I have an issue to go and buy a vibrator. I mentioned that I noticed he only got turned on when I would wear things that either showed off my breasts and backside, and if that was the reason why he couldn't get in the mood for me, he said it would be nice and that he would want to have sex more but it feels degrading to me since we've only been dating for a year and a half and it feels like it's the only way he wants me. What do you guys think, am I being too much or?
