I'd say invite your GF over, close the blinds, put on some music, lower the lights, and say you want to learn to dance with her.
Also, I'm not much of a drinker, but I'd still reccomend a little alcohol. Think of it as using the right tool for the job. Sure you could frame a house with a pair of linesman pliers, but it'd be alot easier to use a hammer.
My GF and I are the two "whitest" people on earth, still we've done the above a couple of times. It can be very sexualy exciting - and you never know what it might lead to
