try doing something unusual or something that turns him on , maybe he has some kind of fetish , like myself I always find certain body piercings or tattoos really sexy , maybe there is something he finds really sexy and once you know what it is could turn him on easier .
A massage is very effective IMO. Might seem strange given that its meant to relax and unwind you, but if done right then he won't be able to resist anything else but sex!
Or another good technique that usually 'wakes' me up is when I'm having a shower and the girl joins you...again he won't be able to resist it (Either in the shower or afterwards!)
The best thing that ever got me out of my daze and confusion when I was tired once, was coming home to see my girl just waiting in my room dressed in this amazing Agent Provocateur lingerie that she had invested in. Blew my mind!
