All sexed out ?? - please give advice.

Ok. I need to know.

My boyfriend and I have been together for 4 years. We live together currently and have a for about 2 years. He never is “horny”. I could be half naked standing in front of him with lingerie and he wouldn’t even flinch. He tells me he really doesn’t have any turn ons which has always bothered me for some reason. I feel like sex should be fun and spontaneous(at least sometimes). He also never wants sex during the day. Only at night. Like before bed basically. It’s never random times. He doesn’t do “foreplay” or like fun kissing.. juuuust has sex with me and goes to bed......

Don’t get me wrong. We are incredibly happy as far as our relationship and being together. But gaaaahhhh. It’s so irritating sometimes. I’m 23 and he’s 25. We should be in that super fun sexy time phase right?? Any advice on what to do? Or things to try? I’m in a rut.

(Also. I know the relationship is about more than just sex but I feel like it’s equally as important)
