Best/favorite way to initiate sex?

Jessica
Ladies, what are your go to ways to initiate sex? My husband and I have been together for 3 years and I still don't know how to get him into it. I definitely have a higher sex drive than him, but most of the time it feels like no matter what I do, he only wants it when HE wants it or when it's a good time for him. 
I know I don't have a perfect body or anything, but I love him so much and I want him to want me. Help!
