Husband doesn’t want sex ?

I’m 27, he’s 31.. been married for 2 1/2 years and ttc low key “without any pressure” for the last year. I feel like he’s never wants to have sex unless he initiates it. He never seems interested when I touch him or joke about it. He never compliments me on my looks or even seems to notice me. I feel like I’m pretty fit and good looking and my concern is that if he doesn’t find me attractive now, what will he think of me in 10,20 years?! Any hints on other ways to get him into it? Make him excited to have sex again? Tips on initiating without feeling like you’ve failed as a female?
