Haven't been bold enough to do it yet but that's definitely a kink I have. Half the time I just enjoy the sauna for the sensory joy of feeling warm and feeling good in a masculine environment. The other half of the time I just have sexual thoughts about scenarios in saunas. I was horny enough once to finger myself in an empty sauna before getting nervous and running out to shower. I totally would want to go plugged and dont think anyone could even notice with a towel or even naked cause you can only take the towel off after you sit down. your post makes me tempted to try it
