Hmmm. See, the thing is, all these things are matters of personal taste. Some are more universal than others, but none are universal. With that in mind, here's what would work on me:
1. Kisses. But not just any kisses, deep kisses. For no apparent reason.
2. Surprises. Surprising a high-desire man with any sexual overture is a challenge, because we think about sex a hundred times a day and certainly every time our wives walk into a room. Surprise him with a nibble at his ear or a kiss on his neck or a hand at his waist a little lower than is generally considered polite, and you'll have his full attention.
3. This may seem really crude to you (or not) but honestly, just walk up and put your hand on his crotch. This leaves him no room for doubt, no room to wonder why you're doing this or that and whether you mean anything sexual by it. Your hand is on his penis. It's clear and straightforward.
4. I've never understood why it is that women seem to pinch butts, but never rub. I palm my wife's bottom and give her a warm, firm rub for a couple of seconds, and I don't know who enjoys it more. Not that there's anything wrong with a friendly pinch or a little smack on the ass.
