Well, if it has to have male strippers involved, I'd go with the originators:
Party Hardcore from
Payserve
Sales went down the drain when OrgyCash fucked up the tours, but now with Payserve's new tours things should be rockin' again.
If just "party" sites, without the male strippers, are ok for you aswell, Payserve also has
Drunk Sex Orgy and
Mad Sex Party.
Then I personally also do well with
College Fuck Parties from
WTF Bucks.
