As I said above, it depends what your expectations are... the show is to celebrate "Erotica" not porn, even though porn as most definetly nudged it's way into the show...
I always remember one of the first ones I went to, must of been like 6 or 7 years ago... a guy clearly in his 70's wearing a silk nighty, another old gentleman in his RAF jacket and a tu tu ! And a guy dressed in leather and a gimp mask being lead round on a lead...
That for me is what the show is about, those that do stuff when the curtains are pulled tight...
The stage show is always good mind, think the torture garden peeps put it on, and yes Dita Von Tease was amazing, as was Masumi Max... The Fuel Girls have done it a few times to and were always good...
So if your in the porn biz, then I guess depending on your role in it, there are some opportunities... loads of shopping ops, for clothes and props... might be some networking opps so take cards, if you dont have them use one of them 50 cards for ?3 machines...
If your after a free sex show then it really isnt going to happen... It sounds like Strictly Broadband might be about the friskiest place in there... and I think the topless bit will probably have tapped nipples, as sure they dont allow nipples... damn they dont even allow that at AEE/Internext in the USA which are porn shows...
Anyways I am thinking of going along myself... armed with my credit card to do a bit of shopping, and my business cards for a little networking... I will be the guy in the pink shoes

Not sure which day yet, probably Friday or Sunday not sure which will be more quite, which is my prefered criteria
