If I don't,it'll never happen. Pointers!?

Patch • First they're sour then they're sweet.
Okay so, I want to take initiative & do something romantic & sexy at home with/for my husband.
 We're pretty broke at the moment, so that's a thing.
Hopefully we get a babysitter so the Kids won't be home.
I'm just not really sure where to even start. I want to do this because if I don't, it'll never happen because he won't take the initiative to do anything like this.
Can someone help, what sort of things can I plan!?
