French has the reputation to love sex. The number and large variety of the backrooms and the cruising bars of Paris will certainly not refute this image! It has some for all tastes, from cleanest to glaucous, from large to small, from enlightened to very dark. Some play on constant theme (100% naked, fisting...), as others vary their special nights. The venues with shower facility are exceptionnal and you will there need to bring your own "showerhead".
To enter you have to pay a cover or to buy a drink before joining the action, often in one of these arched-ceiling basements typical of Paris. Condoms and lube are systematically given at the admission desk or at free disposal. Don't be afraid to claim some if not. He is always a good idea to leave valuables at the cloakroom, not to regret to have thought, for a small time, of another thing than your pockets!
Most of the sex-clubs open late in the evening, some in the afternoon. But most of them have special parties on week-end afternoon. Check the themes and schedules before going.
