I've been once or twice... I am straight but really open minded. Oddly the last time I went the atmosphere was strangely reserved! Everyone seemed intimidated and shy (dressed in skin-tight leather and using co-ed baths ;) Anyway, I don't really know WHY we go- more or less to meet other open minded people... Might I suggest 'fetish night' at Sambuccas? now THAT was a great time. People were really open minded and you get a beautiful, tasteful sexy-ish show for such a good price. Or if you like great music, Twisted element is such a nice bar and the Dj rocks the floor like nothing you've ever heard. And of course there's the Warehouse... awesome times there too! I can honestly say that personally I had way more fun at fetish night then kink night.
