back seat of a Buick in late August was prolly, just as hot.   We were both drenched.

Had (civie) sex many times in my sauna (about 10 yrs ago)..................

when I was riding (bicycle) upwards of 50 mi's a day; my lover (at the time) was a runner.
Had a 2 cup session (2nd pop was GRK which she loved) at low temp setting (lots of water on the rocks!).
We were both drenched/gasping for breath by the finale, but it was AWESOME!!!
Would not try this currently as I'm not in the kind of (cardio) shape required for this level of extreme 'activity'!

Wanting/longing for that same 'strenuous' level of session, I've bought a trainer and started riding again (indoors).
Hopefully by summer, I'll be back to at least 30 mi's a day.

btw - still have the sauna

I like to get sweaty the old-fashion way

with some hot naughty fun.I would think with the sauna heat and body temp it would be way too hot.Nobody wants to pass out trying to cum I rather have him pass out in bed in a hot erotic environment(not the sauna)

a true Finlander from Northern Minnesota!  I grew up with a sauna in the home, at the lake...had plenty of wild times in the sauna.  I have to say, though, the heat itself makes you weak and wobbly.  Add some wild (or even mild) sex to that, and it's just too much.  Add a beer or two, and you might as well forget the sex.  Hope you know CPR!

I'd save it for after the sauna in the dressing room, but not in the steam room.
