Barely any sex and engaged

My fiancé and I are definitely in love, but I feel like there's this weird break in our relationship. When we first were a couple we had sex a lot. I got  on the birth control shot and it made sex very painful until I got the birth control all out of my system. We would try to have sex during this but it wouldn't work.
Now  I'm off And sex isn't painful anymore (around a year since bc). 
Our sex life is like 1-3 a month. Usually 2 times. 
I always come on to him but he thinks I'm overly sexual. What's going on??
