help please!!!!!!!!

Okay so my fiancé doesn't care much for sex, like we could go a week without sex and then him actually want to. What're some things to get to want to do it more without asking or showing him I want to have sex? Sounds weird right but I want him to want me l want him to ask for him. I want him to show me off and shit, he doesn't. I want him to slap my butt and kiss me infront of people and in public and shit. He doesn't even touch me in public.  What're some things I could do?
