Disapppinted, embarrassed.. advice?

So, a while ago, I bought these really nice underwear, a red thong which is strappy and has cut out bits at the side. Ive been hyping it up ever since I got them to my boyfriend, and I finally wear them for the first time.. and he looks at them and just doesn’t say anything..

Firstly, earlier that day, I had sent him a message like ‘I’m wearing some really nice underwear😍’ and he just does not acknowledge the message and changes the topic. We have been together almost two years, we used to sext a lot and occasionally send like cheeky underwear pictures etc. But, for the past 6 months, he has no interest in me sexually whatsoever. We used to have sex ALL the time, and yeah, we still have sex quite a bit, but it’s just not the same. He sees me as cute and wants to cuddle all the time and of course that’s fine, but I wanna feel sexy too you know? I want that spice in our relationship. I want him to look at me, in those underwear like he used to with a similar red thong I wore, and he like ‘I want to fuck you’. I’m just so embarrassed. I really tried to dress up and look nice for him, and he just doesn’t care anymore and we have no fun or spice in our relationship. I can’t even make a sexual joke he just doesn’t acknowledge them. Is it because I’m ugly? Because I’m trying so hard to look attractive:( what’s more, is I have not orgasmed from sex in 10 months.

I’m frustrated and really making an effort to look good.. I just feel so embarrassed.. he did the same on New Year’s eve when we spent it together and I was wearing a G string for the first time and he just went to sleep.. I’m just embarrassed and disappointed for dressing in those underwear and showing him them.. I feel like an idiot. An ugly idiot.
