Is not having sex, causing my anxiety?!

So my boyfriend and I used to have sex like every day! But obviously as we’ve been together longer, we haven’t had sex as often. But recently i’ve been finding myself trying to get things going, and he just falls asleep, and I have a massive anxiety attack while he’s fast asleep. Thoughts are going through my head like “he doesn’t want me anymore, is he having sex with someone else and doesn’t need me anymore” stuff like that. This happens very frequently! Tonight was our one year anniversary and I was hoping to get some action, so I did my face all good and my hair, shaved everything! Tried to get things going... and nothing. He just fell sleep. Now I know he works all day and works hard, but like... come on. I’m feeling so insecure, is all of this unhealthy? What do you think I should do to help this? Thanks girlies.
