Hire me? Just kidding :)
I would becareful. I guess I'm biased and I'm sure those girls work hard too, but I know I would have issues with stranger types. At least with a "escort" you would have the one time thing, with no strings and probably never ever see that person again. I was going through a similar thing with my guy, and I was having issues trying to see him with another woman. Oddly, one particular woman, who I considered my canadian twin!, I didn't have a problem with... but for some reason others I did have a problem with. But my swinging experience has been a little Choppy :)
Anyways, I live in Vegas and I could show you around to some things if you like. I am not big on the club scenes but there are other neat things to see around here. Just a thought :) You could also try the Green Door while in town to sort of "dip" into the swinger scene.
