Fiancé only has sexy on his terms?

What should I do? My fiancé never wants to have sex when I want to. I am ALWAYS down to have sex. But everytime I try to tell him I’m in the mood or want to he says no. But everytime he’s in the mood I always say yes. I know normally it’s the other way around and I don’t like pressuring him to have sex with me because I know what it’s like to be pressured into sec but fuck. Last night I even took a shower and shaved and laid next to him half naked and he just rolled over and went to sleep 😞 is there something wrong with me?
