Hello mandrake. I can tell you about few clubs. First about strip clubs. If you do not want sex, just to see a lots of beautiful girls naked dancing by the pole, you can go to stripclub Gold Fingers, Hot Peppers, Karioca or others. If you want to see strip show and at the same club you want nice and good girls in bedm, then I can highly recommand FKK prague. I have been there more times and I was never satisfied. Call them and they will send you taxi. It is different club then others in Prague. If you want extras like owo, cim or cif, you will not get them in other clubs legally, but in FKK yes. And please, if you will go there, take some photos for us!
Also there are other clubs in the center like Darling, Atlas, K5 or so. If you like bigger prices and clubs packed with people every night.... But i think you can find some nice girls there too. I am not really sure about sexpark. It is same cheap as the streetwalkers and the girls are having sex like 10 or 15 times in a day... I think you can imagine sex with girl like this. My experience was very bad, it was like machine....
Streetwalkers are not good choice especially if you are foreigner. They are mostly gypsies who are just acting like prostitutes and they will take your cock into one hand and with other hand will find your wallet. Maybe they will not even touch you cock.... Also, they can take you "to discreet place where we will be alone" and there will wait another 2-5 gypsy guys with knives and you will be lucky to get back home healthy. All the streetwalkers are working in the street because they need money for drugs, they are addicted. They cannot go to any club because they take drugs too much, so they will do anything and everything to get the money from the customer. They will also do sex without condom, or blowjob without.. But they do it to many and many7 customers before you too, so there is extremely strong chance to get STDs...
I would prefer club, for sure. Good luck and dont forget to give us a long report!
