Never been to one of those, although there have been a few in So FLa, so I don't really know how it all goes down at the party.  Don't think there are too many guys there if there are only about 5 girls.  They are kinda costly for the guys, I believe, but they seemed to be a lot of fun, after seeing some pics.  It probably helps if you know the host, but if you don't, there would likely be some pretty heavy screening in order to get an invite.

I would suggest you contact the host/hostess directly..

Don't expect any real answers to a post of this nature. What is it about "PRIVATE" that you don't understand.

You are also posting under alias with questions that are improperly framed and I question your motivation.

Haven't been but know guys who have been at times.  Their descriptions are there 2 to 3 x the number of guys as women.  The women are kept pretty buisy and after a little while it's pretty much one hops off and the next one hops on.  Not my thing, but others said it was a blast and have gone back for more.

Probably lots of variation n how they're run.

i went to one in London, UK and done one in Manchester, UK last year. They were pretty awesome but you gotta not be a shy boy and not mind seeing a bunch of other guys and gals getting it on, and not be intimidated, if you can get passed that and make conversation with some of the girls you will have a blast. I personally didnt partake in DATY but did receive BBJ and had a blast, my problem was that i just cant perform more than 3 times in one event, and the third one was pushing it!
