I looked up and there another RLD in Frankfurt near the main train station, do any of you know the name of the street please? if possible the building no. too please?
Main RLD = Bahnhofsviertel (very close to main train station, AKA Frankfurt Hauptbahnhof)
Secondary RLD = Breite Gasse (close to Konstablerwache metro station)
Also keep in mind how to get to places such as FKK Sharks, Oase, as well as secondary cities such as Coloogne/Koln, Bochum, etc. as they are also well regarded by many punters and easy to visit from Frankfurt. By far the easiest, and most would argue best, would be the FKKs.
Frankfurt is a great shout ranging from €20 - €50 per punt, check out Wiki-sex guide as there is a list of brothels with street names covering the area by the train station and also Breite Gasse. Early morning punts seem to be the cheapest.
Yeah, the earlier the better, as there are less dodgy people out earlier in the day. Later at night, especially Friday - Sunday nights, a lot of people will go to the laufhauses in the Bahnhofsviertel and walk up and down the buildings in groups. It can become congested and rather annoying, and some punters might be turned off by others watching them browse and negotiate.
The last time I was in the area, I visited both RLDs before noon and I was often the only guy going up and down the stairs. Some of the buildings in the Bahnhofsviertel were lacking prostitutes, but there were a lot of women in the Breite Gasse as that time waiting for a customer. If necessary, a punter could certainly use that to his advantage.
