As a teenage girl i gotta say, Lacoste cologne, the one in the clear bottle with the pink on it (it might be red i dont remember) is such a turn on if you dont over apply. But also, I seem to like, not be able to keep away from a guy wearing victorias secret very sexy for men. And I know I'm not the only one...
but for something less conspicuous, try any of the abercrombie& fitch colognes.
