I went to Body Bio a couple of weeks ago and was surprised to fnd that it is not really a Sauna. it is a s*x club and you can either opt to enter fully clothed (cheap entry fee) or you can have a locker for a bit more and shed your inhibitions..!
I did the latter and found that the activity in the darkrooms was amazing. Although most of the clients are 40+ they are horny as hell and within half an hour I had been sucked be 5 or 6 guys! Also there are plenty of places to go if you want more (which I did!!)
The place was great value and I will be going back every time I visit the city.
