Found myself at the St Paul metro station on a rainy Tuesday afternoon, so I thought I'd stop by the sauna and steam room to warm up for a bit, and get to see what a mixed naturist sauna in Paris was like. It was really a lovely experience. Yes, the facility is on the small side, not the grand scale and pleasing aesthetics you might find in Baden-Baden or the like, but it was functional and war, the person at the front desk was pleasant, and the whole thing made me feel comfortable and cared for. There's one dry sauna, one steam room, a small swimming pool with single shower, a locker room, massage rooms up a flight of stairs. If you want a massage, your options are 30, 45, or 60 minutes, and regular or naturist (you're naked either way, but in a naturist massage the masseuse or masseur is as well). I tried the naturist massage and it was thorough and professional, with good pressure, and having the masseuse naked was a fun change. (No, there was no "happy ending" offered or any other sexual services. But it's nice to be in a setting where the ordinary anatomical responses a man might experience are treated as no big deal. The masseuse just gave me a palmful of massage oil so I could take care of it for myself.) The gender mix was definitely tilted toward men, but it wasn't 10-to-1, probably more like 5-to-2 while I was there. And everyone was polite and respectful. Average age probably 50+, but that's typical of naturist facilities. There was a lounge where you could relax and have tea, but I didn't use it. Just enjoyed my couple of hours in the sauna and steam and pool, and the massage, and went home feeling marvelously relaxed and refreshed. Very strongly recommended!
