Initiating Sex - Help!

I love having sex with my husband. I am so attracted to him and we have amazing sex. But we have a problem! 
I don't know how/get uncomfortable initiating sex. 
I will literally say "want to bang?" before I would kiss him or make a sexual move. I have no idea why I feel so awkward or uncomfortable with it!! Has anyone else had this problem, or have any advice about how to get over it!? 
We have a good sex life, but I know he wishes I made the first move more often (like, ever lol).
