Heeellllpppp!!!

Soooooo... Lol. I'm a very awkward person and I'm trying to plan a romantic day for me and my fiancé. I want to do something cute and special for him which I have no problems setting the mood and cooking for him but I don't know how to go about initiating sex with him. He usually initiates it because I get so scared and awkward every time I think about doing it. Any suggestions?
