In the Bournemouth/Poole area there used to be a local punting site that was fairly active with both escorts and punters. the site owners used to arrange a couple of social do's per year, attended by any of the girls that wanted to go (usually about 5 or 6) and a number (somewhere between 10 and 20) of invited guys (the active and girl recommended ones) and these were good events.
I was fortunate enough to be one of those invited and yes, it was a bit weird to meet other punters at first but soon overcame any shyness. It helped then with any reviews or recommendations made by these guys either on that site or on AW. it was also good to create a bit of a punting network with suggestions of ideas to help each other. For other reasons, the site unfortunately slowly then "died" and whilst still (i think) technically in existance, noone goes on it this days and it is as good as dead. (hope i am not breaking any UKP rules by refering to another site, if so my aplogies).
one of the other guys then did a smaller version of these social meet ups at his place with a smaller cicle of invited girls and guys and also the opportunity to spend a little private time with a girl if both parties wanted to. so a bit like "a party" but by invitation only, no entrance fee and no naked other guys to worry about (happened in private). Unfortunately this too have stopped now but they were fun and benificial whilst they lasted.
so, yes in the past i have but not anymore.
