My boyfriend isn't as direct about his horniness as I'd really like him to be?

I'd love for him to be less shy about it and more open and direct when he's "in the mood". He's been getting a bit better about it, but I'm more the type of person who likes to be teased and whatnot. I know what I like and what I want, and I want him to be more straightforward without me having to tell him all the time...it gets old, lol. Any suggestions?
