I need help with a sensitive topic.

My boyfriend and I have been dating for a year now and everything has been perfect, I really love him and enjoy spending time with him, he’s my best friend. That all changes when we’re in the bedroom. He becomes a little forceful and begins to touch me when I tell him not to. I don’t enjoy sex much, not because its not good but because it simply never really caught my attention much and I would rather do many other things with my SO than that. He gets annoyed with me when I don’t have sex with him and gets annoyed when I do because “I don’t look like I’m enjoying it.” I’m so anxious to be in bed with him or alone with him because I’m scared to start another fight over the same thing. As I type this out, I realize it’s not healthy but he’s a good guy and he apologizes the next day for “forcing me into sex.” I love him but I’m so confused as to what to do. This isn’t rape, right?
