What do I do?

So I’ve been seeing this guy and the first few months we had great sexual chemistry honestly everything I love he did foreplay he would give it to me 3-4 times a week it was heaven. But lately I guess things have calmed down and he’s been denying me more often and sex basically went to 1-2 times a week and I’m lucky if I get that second time. I’ve bought lingerie(bc I LOVE lingerie ) and he denied me then as well so now I have no self esteem to wear lingerie anymore. I also stopped asking bc I get denied. So I thought okay so this is normal he just has a lower sex drive than me whatever. But now he’s got kinda lazy in bed. And I love him so I feel bad saying it but my start kissing and I start kissing his neck and lays back and enjoys it, but the thing is he doesn’t reciprocate, he won’t kiss my neck anymore or my breasts nothing. He’ll rub me sometimes but usually it’s just me kissing his neck and then I get frustrated from the lack of reciprocity and either I’ll stop and that’s it for us. Or I’ll just start sucking his dick and then that’s when I have to do the work and that’s it.

Leaving is not an option but I’m starting to get frustrated at him not playing with me. I tried to talk to him and he got defensive and it didn’t work. I haven’t talked to him since but I’m starting to feel like maybe it’s something wrong with me.

I want to add that things started changing when he started gaming again (he didn’t game when we first met it’s about 2 months recent) he wakes up and immediately starts gaming and then will hop off for a couple hours and to eat shower ect. Then hop on until past midnight and when I ask for some after, he’s too sleepy, hence the no reciprocity thing.
