Feeling rejected by husband, like sex is only on his terms

I posted this in a marriage advice sub, but the comments were looking a little incel-ish. Lol.

I'm looking for advice on how to handle rejection from my husband, when we've already had a lot of talks about this topic and we're already in marriage counseling (but are currently working more on communication issues).

Our sex life was amazing when we first got together, very liberating and fun. But once we became more committed, I noticed that changed.

I'm pretty timid sexually, so I figure it can be surprising when I try to initiate intimacy. But it makes it that much harder to cope with for me. It takes a lot of courage for me to "put myself out there" with my husband, which I've explained to him many times.

It feels like sex is only on his terms, only when HE'S in the mood. If I'm trying to tell him how attractive I find him or show affection hoping it'll lead to intimacy.. he kind of just acts put off. Then, when we do have sex at a different time, it's always the same routine. It 100% feels like the goal every time is for him to get off as quickly as possible. No desire for connection, very little foreplay, and what I like seems to hardly be a factor.

I've talked to him about it and told him I don't always feel comfortable speaking up in the middle of sex, and I've told him ways that I feel we can connect more when we're intimate. We've had that talk many times over the years, in fact. But it doesn't seem to change.

I feel embarassed. I've been working out, doing my hair and makeup more, outright asking him to pay attention to me. But he hardly seems to notice.

Like I've said, we're in counseling, but we're also in a rough season of life. With two kids at home, one who's autistic, and no support system of our own, it's hard to find the time and energy to work on our marriage more than we already are. Especially when my husband doesn't even seem to recognize the issue.

TL;DR: I feel constantly rejected sexually by my husband, and we've talked many times about it over the years. I'm starting to wonder if he's even attracted to me. How do I cope, if it doesn't look like it's changing anytime soon? I'm starting to feel pretty lonely in this marriage.
