How to know if your partner still finds you attractive

hello, I (21F) really wanna know if any of you guys have tips to check or know if your partner is still sexually attracted to you. My husband (21M) has been distant when it comes to physical contact.
some emotional connection is also missing from time to time but not as much as physical. I couldn’t help but wonder if maybe he just doesn’t find me attractive anymore.
I try to initiate a lot of physical activity but it’s like he doesn’t get the hit even though i’m pretty straight forward.
I communicate pretty often with him. I just feel really insecure and alone at the moment and it’s like he can’t tell at all. if anyone has any advice i would love to hear it. thanks

TL;DR: i’m trying to figure out how to know if your partner still finds you attractive. (21F) & (21M)
