What does your spouse do to tell you he is in the mood?

My husband and I have been married for 5 years and I ALWAYS have to initiate sex... when we were first married this really helped as I have been hurt sexual, but it's been almost 10 years since it happened and I have healed so much. Sometime I just want him to initiate sex and be sexy about it!! I've told him this and gives me this blank look and asks, "what do I do to tell you?" 
So! Ladies and gents, what does your SO do to you to tell you they are in the mood?
