uuuhhhhh....just tell him no? say it firmly straight to his face everytime he asks and he'll get the message soon enough.
Lap dance? Strip joint pushing dollar bills into g-strings while the pretty girl eye contacts you longingly? LOL... Please... Talk about lame. If your "friend" wants to have physical contact with the opposite sex, tell him to stop beating around the bush (no pun intended) and just go get laid; bada bing bada boom. Over and done with. That's a whole lot better than breathing in second hand smoke all night, listening to yesterday's hip hop so loud and long that your eardrums bleed, and waking up with a pounding hangover, just for the transient and solitary joy of slipping a dollar or three thousand into some wiggling crotch for a few seconds of cheap feel each time. If your friend wants sex, tell him its much easier to cut to the chase; go get it and leave you alone, unless he offers to buy you a piece of ass too. If that's the case, then bring a box of Trojans and enjoy yourself. Ralph
