Find sex in Germany is very easy. Germany is probably the country where there are the largest number of brothels and sex-clubs in the World. Prostitution is legalised and organised since 2002 and many brothels, called FKK saunaclubs are wellness and beauty palaces.
The most famous kind of brothels in Germany is called FKK saunaclub. It is a mix of wellness center and sex-club. The place looks like a privat wellness club with restaurant, swimming pool, sauna, etc. But it is frequented by independant prostitutes as well with who you can have sex in rooms which are available in the club.
In addition to fkk saunaclub, there are clubs called Pauschalclub or partytreff clubs which are flat rate sex-club. In this kind of sex-clubs you have to pay an entrance fee, and then, you can enjoy all sex you want with any girl you want. These clubs often deal with hardcore sex and orgy sex.
Eventually there are classic brothels wich are often luxurious places as well, and eros centers called Laufhause wich are cheap brothels located in the cities centers. Laufhaus are sex center where prostitutes rent rooms and manage them themselves. Sex services are cheaper than in a classic brothel but services and conveniences are more simple.
