Caution using an escort as a stripper. Unless they have actually done it before (as opposed to just claim to have) they will be rabbits in the headlights in my experience.
Lapdancing and the confidence to be naked in front of a room of blokes is not the same as having sex with one person.
Some of the best events I've organised are where a group of known more "naughty" strippers (but not escorts) came from a larger City club to a private party. If that private party offers a guaranteed amount and isn't on a friday or saturday night so much the better.
