My experience has been that it is a social gathering primarily.  The ones I have attended take place at a public venue like a resstaurant or pub so things are pretty laid back.

We mix and mingle, laugh and just get to meet each other in a social setting.  Sure sometimes arrangements are made and couples, or trios, slip away together, but mostly it is a chance to see the other in person and see if the chemistry is good.

But yes there are sometimes event that take place in a hotel bar and many have already taken rooms upstairs so they can conviently go upstairs with a lady or two of their liking.

Sometimes they are held in private homes with naughty games and door prizes, blow job contest, etc.  But I refrain from that crowd in general.  Not that I am a prude but generally I only know a limited number of the folks there and prefer to keep things like that with a group of folks I know and trust.

Getting invited to a M&G can be difficult for a newbie because references from a lady in attendance is frequently required.

I've been to 3 M & G.  Two were held in a hotel suite and one was in a hotel meeting room set cocktail reception style.  The events in the suite were a little more private so there was more flirting.

In some cases I had a date lined up for afterwards.  You can wait until the M & G and see what catches your eye.  Just have an envelope with you with enough cash for a multi-hr. date and/or a threesome.

There is more information on the M & G board.

Usually no "hanky panky" goes on for many reasons.  First, if its held at a residence, in the event of LE, the host does not want to be charged with operating a brothel.  If in a public venue such as a hotel, unless you have reserved a room at that hotel the organizers do not want to take any chances.  If at a restaurant or bar, management normally frowns on public indecency.  lol

What they do offer, a chance to meet ladies "face-to-face."  Perhaps they blur their photos.  If so, you can see the real face.  Or perhaps you are shy and getting a chance to talk to a provider or two will make it easier for you when you do set up an appointment.

Just use your common sense about attending.  If its at a public place and you live in the area, you take a chance of a "friend of the family" seeing you there and telling your S/O.
