If you and your guy have sex with each other.. Give him the best sex ever! Be naughty, spicy and fulfil all his fantasies. Make the day romantic for your guy, buy him romantic gifts, spice up the room, and you know the rest.
If you and your guy are not into sex blah blah.. Give him the best make out session ever. Let your tongues to magic, and buy him a gift he's been wanting for soo long.
Same goes for the guys. Just make the day.. really special, go on a real date.. Infact, you can buy her the dress she'll wear to the date. If you cant buy a dress... buy her some ices, necklaces and earings to spice her outfit up. Take her to a restuarant.. hire one room for like 2 hours, and decorate it urself.. or with the help of the restaurant workers. Give her a gift she's been wanting for soo long. And make out of after the dinner.
Carry mints with you cos .. of them godforsaking onnions.
