Hi, I'm not sure if you're the same girl I sent advice to about this or not, but I used to be an exotic dancer.
Clothes- figure out what kind of lingirie he likes, go to triangles, sex shops, or victoria secret for the clothes and shoes.
You're going to want music, preferably anything you can feel sexy to or that can give you an excitment to dance.
Do your hair and makeup in ways he hasn't seen.
Fix the lighting- I like using candles, it sets the sexual/romantic mood, and it kinda hides any flaws you feel/think you might have.
You don't put your butt or crocth in his face lol.. Well you can, if you want to be nasty nasty...
Put him in the middle of a clean room sitting in a chair, with the music and candles (or dim the lights)
Make your sexy appearance in your new "skin"
Flirt around the room playing with your hair, clothes, breast, whatever.
Do some flirtatious moves around him and the chair, letting him smell your hair, but no touching yet.
Yes look and smile at him, he wants you to have a good time too.
Do some floor moves (get carmen electra lapdance "workout" videos they give wonderful ideas)
Finally get close to him, but don't sit on him, lick his ear, breathe in his ear, whisper something naughty, like "do you like this baby?"
Turn around and rub your leg all the way down to the floor, when you see him looking at you, smack your ass, or snap your underwear.
You can strip your clothes off one by one, like take off your bra/top and wrap it around his neck.
Finally sit on him, and do whatever from there, more dancing, grinding, whatever.
Get creative and have fun the more fun and excitement you have, the better!
