I was in Hannover last month and planned to hobby a bit, so did some research on both FKK and the red-light area. It was clear in about 30 seconds that the red-light area was a no-go - there are 2 streets a few minutes walk from the Hauptbahnhoff, where all of the clubs/hookers/peep shows/etc, are all located. Forget the names of the streets, but they are a block away from the C & A store, in the central shopping district. Anyway, major dodgy looking area, and this was in the middle of the day! No way would I walk the streets after dark. Shabby, smelly, skanky, no thanks. I moved on to the next alternative, the FKK Villa, and was I glad I did. It was about a 11-12 Euro taxi ride from the HBF, 7-8 minutes. Entry is 60 Euro, and after paying, one of the girls shows first-timers around, and explains the system. 50 Euro for FS and a BJ, for 30 minutes, and all extras are to be negotiated up front with the girls. Extras vary from girl to girl, so you can skip from one to another until you find the combination you like. You get a locker in the change room, and then jump in the showers. Everything was clean and spotless, and once done, you move into the main club area. Once you've found the girl of your dreams, you move upstairs to a nice size room, clean, well lit, well ventilated. You take care of business, then you both go back down to the locker room where you then pay the girl for services rendered. The whole process is so civilized and easy, it makes you wonder why FKK brothels aren't the norm all over the world. After paying, you rinse off, put on a robe, and then roam the different rooms (bar area, tv room, massage room, etc...)chatting up the ladies, doing the legwork on finding your next conquest.
All in all, a brilliant system, and easily a much more comfortable arrangement than trying to hook up with a SW, or risking shacking up with a girl in her place (who knows who's in the closet?). For you cheapskates out there, get over it. Pay the money, and have an amazing, safe, easy-going time. It may not be the cheapest hobbying, but it is easily one of the best arrangements I've ever come across.
For the details, the girls I spoke to (about 12), I could have partied with at least 7 or 8. Every extra was on the menu, but I wasn't looking for anything far out, so I never got prices, but I can imagine extras going from 20-50 Euro (CIM to anal). Girls were solid 7-8's, but if tats turn you off, this could be a problem as ink seems very popular. The 2 ladies I hooked up with were both German, but it appears that FKK's are a United Nations of talent, with a heavy dose of Poles, Russian, Ukranians, etc...No dogs, nothing but smiling faces. One of the best parts is that unlike American broads, these girls seemed to be all-natural - no bolt-ons, no fake lips. Hot, natural looking girls.
Summary: big thumbs-up.
