Depends on the person and the sex.
For me, a guy, I would say....
1. A hummer. You can lease one for like $650

2. A kick ass play, dinner(lobster), and a bitchin hotel room, sex included.

Limo, tux, the works....
3. Ski resort trip
Las Vegas trip
beach trip
boating on a 3 sail ship (schooner), bed n breakfast in Beliz
But give him sailing lessons first! Then the tickets and trip at the bottom of the box! He learns to sail... and gets to actually do it!

4. Membership to a guy's spa/gym/private club top of the line.
Cant think of anything else at the moment...
Small shit could be...
playstation/xbox/game cube
flat screen TV
DVD set
etc...
