You want him to REMEMBER you. Guys are dumb. The last thing in, is going to be the last thing he remembers about you.
Therefore, I suggest that you give him YOU. Invite him to dinner at your favorite romantic restaurant. Buy a good Champaign. Seduce him... Take him to a hotel. Wear sexy underwear. Do something different. Put on a little shorty maids dress. Then do him like you've never done him before...
Personally, I'd like a present like that...... If you couldn't tell already.
