(24F) Is my relationship with my boyfriend(19M) hopeless?

*Throwaway account, don't want friends to see

I learned recently that my boyfriend is sexually unsatisfied in our relationship and it's really blindsided me. I thought our sex life was great because we do it quite often and he's a very receptive lover. But two days ago I found him masturbating in the bathroom after we had sex. Long story short we had talk and it's because he wants to do anal, and he imagines doing it with me. I knew he liked anal but I didn't really think it was that big a deal because he's never pressured me about it even once, just asked a few times. And when I said no, he never asked again.

To make things worse, when I asked him if this would be a problem for our relationship, he tells me : "Of course not baby I love you. I couldn't just stop loving you because you don't satisfy me all the time." And while I appreciate him being reasonable, it still doesn't sit well with me. I like sex, I'm good at it, and this was the first time I'd ever been told otherwise.

I wanted to please him. So I asked about any other kinks he's been hiding from me. And you know what this guy said? Pegging. Like what the fuck?

I'm starting to feel like I just wasted four years of my life. When I first met Elijah I was so drawn to him. To his composure, his maturity, his kindness, how when he spoke, people just listened. He wasn't perfect, but he was still young and he had so much potential.

I thought I could help him become the man he wanted to be, but he hasn't developed as much as I thought he would. When I first started pursuing him, he was "secretly" dating a boy in his class, and it wasn't until I explained how ashamed his father would be if he found out, that I finally convinced him to dump the kid. Idk I thought he would of grown out of it by now. I mean he's not a complete fag, but he's still too comfortable with his feminine side if you get what I mean.

I don't want to break his heart, but at the same time, I can't keep giving him my all and still get nothing in return.

Do you guys think there's any salvaging this? I'm open to ideas about dealing with his sexuality. I'm just not sure if he's committed enough to actually change.
