In Germany there are many houses where 5 to 10 girls work there per shift. You enter the house by paying a fee and once inside you are given a locker to put your stuff away after that you are on your own, free to walk around and have fun with any girl(s) as often as you can handle it until the closing time, all for equivalent of about $500 USD.
In some other clubs you pay a small entrance fee ($100) for admission and then by number of the condom you use. There is a condom girl who walks around and dispense condoms but also keep track of the condoms you use, all in all this happens in open, just like a big gangbang party with open bar, whirlpool & sauna !
