Swinger tourists in Prague

Hi.
Me and my wife will be visiting Prague this Tuesday and leaving on Friday. We have read most of the discussions about the different clubs in town and we are looking for at least two visits during our stay.
What we really hope to meet is couples around 20-40 years old. Is Paradiso Day Party on Wednesdays something that many people go to? And if so.. Are they younger?
Is it only Fantasy that is having a party on Thursday?
You may answer in česky if you want to. Thank you.

To be honest, I am not sure if you can find party with young couples on different day than Friday or Saturday. Different story would be, if you are looking for single men too. Fantasy is probably visited the most by younger people. You can try Lublanska, but you need to expect lot of single men. Probably the same with with Bunkr (never been there). In Paradiso, its likely to see (and join) some action, but I would expect people of age out of your desired range.

Thursday lonely guys are admitted in Fantasy, so not sure if its exactly ur cup of tea. Paradiso Wednesday party - it's mostly work colleagues fucking like crazy, but the party ends at 6pm :), Wednesday in Fantasy starts later, a bit more calm than in Para, but still good usually. Fridays are ok in both P. and F.
Other clubs are shitholes or have everwhelming lonely jerkers audience and very few cpls.
