Boyfriend thinks I'm not attracted to him.

My SO and I have had this issue for a bit now. We talk about it and then it seems to be fine and then he'll bring it up again one day. He says the reason he thinks I'm not attracted to him, or that he doesn't turn me on is because it takes me a long time to orgasm. I have tried explaining that most women need foreplay (which he doesn't really like doing) and clitoral stimulation (which again I do myself). And then sometimes even doing those things I don't orgasm. I have told him before that if I wasn't attracted to him I wouldn't be dating him and I wouldn't want to have sex with him all the time. I also have to use lube now as I had a baby 6 months ago and things just aren't the same. Again I tell him that has nothing to do with him.

I am kind of at my wits end because I feel bad if I don't orgasm but then it makes it hard to really enjoy the sex.

If anyone has any advice on how I can maybe explain things differently or what other things to try, I would appreciate it!
