I'm losing interest in my boyfriend

Me (19f) and my boyfriend (20m) have been dating for 9 months. However, lately I've been feeling emotionally detached and feeling no excitement whatsoever. I feel like some things might have been building up over time, but I'm not sure. There's a few points to cover.
For example, whenever we go to a caf? or a restaurant, I feel like he doesn't care enough to put some effort into his appearance. I always make sure to dress up nicely, do my hair, put on some makeup, jewelry, wear perfume, etc etc. He never does any of that, he wears 3 different colors that look bad together, basketball shorts, doesn't shave, his hair stays the same way it was when he woke up, he doesn't wear a watch, no perfume, etc. One time I made a comment about it saying how i wish he would dress more nicely since we are going to a fairly fancy restaurant for some desserts and he got mad at me, saying how he wouldn't say that to me or that he doesn't care if I'm not dressed nicely. The thing is, I know that you will like me regardless, but I still want to show you that I'm willing to put in effort and dress well, since I like you. I don't think that you should only do that while you're trying to win over a person before dating them.
Another thing, intimacy. Whenever we go to his place, that leads to us having sex. I come over, we put on some tv show, and then we do it after a while. And he always initiates it through flirting and touching. Sometimes I do too obviously, but I often wish we could just hang out without sleeping together. Sometimes I come over thinking to myself that I don't want to do it that day, but he initiates and after a while we do it either way. If not that, I give him head. What annoys me is that sometimes he starts touching me, and then asks for head. Like, finish what you started?? So then I give him head... And that's the end of it. We weren't at his place for a week or two, and he asked me to come over today, but right now I feel 0 desire for any kind of intimacy, I don't even feel like making out or cuddling.
Also, when making plans, he never says anything precisely. He goes somewhere and tells me that we will meet at 6, then he comes home at 7 and we meet at 7.30. Okay, he was with his parents somewhere, I get it. But even when we go out he always makes me decide where. I wish he would put in more effort in planning out a date for us. I'm sick of the "you decide" or "it's up to you". He pays 70% of the time so I feel bad pointing out the other things that I'm unhappy with, but the thing is I don't care who pays, I have money too.
Idk how to bring any of this up, and I feel like he won't react well to this. Any advice?
TL;DR, I'm getting bored of my boyfriend because of certain things that I don't exactly know how to fix.

Seems as though he's been married to you for a few years now as in he doesn't care what he wears because he's comfortable around you and he doesn't need to attract anyone else's attention because he's satisfied being with you.
