Well, totally not properly, but kinda feeling my way...I tried to hold myself upside down on a lamp post last night. Failed at that. I can kinda see it can be done with some practice though. I would say it is easier for a smaller thinner woman, than a great chunk of man swinging around with his thick arms and legs ...(perhaps I could just talk like that and get the women excited?)
carmen electra has a series of workout DVDs on stripping, lap dancing, and i think pole dancing might be one. there's tons of sexual dancing how-to DVDs out there though
