First of all, are you after a routine, an effect or do you want us to build you a full Act. . . an act is something entirely different and I usually get several hundred dollars an hour in helping people create that sort of thing. . .
Ok. . . not really, but creating an ACT is a lot more involved.
What you need is inspiration. . . a story line, a poem or love song (classical music even) that ties to the theme of love and romance or raunchy leather sex or whatever you equate such things to. Copperfield had some awesome routines along these lines such as his classic "The Attic"
You say Stage. . . big illusions or simple effects?
I can script you out a program with big illusions with no problem but do you have the budget to make it happen and if so, do you have the time to pull it together? (HINT: No You Don't Have Enough Time. . . a minimum of 4-6 months to make such a thing happen CORRECTLY. . . but then again, that kind of goes with anything other than a basic set of effects).
Routines like French Kiss can be presented with a less corny, more romantic angle. There is the the Floating Rose routine by Kevin James that can create such a feeling but to do such a tribute on stage it would be best to choreograph a sequence of things with a partner so you can tell a story. . . this is what is known as An Act.
Given your apparent age I'd discourage you from approaching Mentalism and couple related routines other than maybe certain mental magic bits. . . I believe the effect is called DECISIONS, DECISIONS by Ted Lesley, it involves two decks of cards, the female selects a card first and then the male spreads and searched through the second deck and finds a card that just stands out to him. . . at the end the cards match proving they are compatible. Cute $25.00 routine (when I bought it). . . the effect uses a method I loathe but for a magician it would be perfectly fine.
I remember seeing someone do a love story bit with a deck of cards in which one of the Jacks is pursuing a queen. . . it's similar to the Bellhop bit Mallone does but I haven't a clue where to find it other than it's in one of the older books, probably Marlow or Scarnes.
Hope this helps
