20. Wear Perfume
This tip might sound silly or superficial, but believe it or not, guys like that women have signature scents. One of my old boyfriends actually still remembers mine from high school! Don't douse yourself with perfume, but pick a simple, flirty or sexy perfume and apply just a little. Wear the same one each time you're around him. Unless he buys you a new one, which might signify he doesn't like the one you chose, chances are he'll love that you smell the same way each time you're around him. It's a sense of comfort, seduction and romance all wrapped up in one!
