So my boyfriend(m23), who has been living with me, confessed again that he doesn't enjoy having sex with me because, in his words, I'm "boring." He said he avoids asking me for sexual favors because of it. Just now, he mentioned he was going to "rub one out," so I went to make us breakfast, but honestly, I feel like a complete idiot—or worse, like a cuck.

For context: I like having sex, but he's said the problem is that I don't orgasm (which I’ve struggled with) and that I don't imitate dirty talk. We've been dating for 4 months, and this feels like such a big deal so early on. On top of that, he’s told me he doubts my feelings for him.

The thing is, I don’t want to break up. He’s genuinely a good person, and I really care about him. The problem is obviously me, but I don’t even know where to start. I've never been in a relationship where this was an issue before. What can I even do to fix this? Is it possible to save us, or am I kidding myself?
