Not at all. I'm not saying separate gender saunas should be abolished, I merely make a case for the alternative.

When me and my partner chose a gym to go to, a mixed sauna was among the positives. Neither of us would like it if it were separate.

Should you choose one, you're free to stick to those with separate options. It's alright. I simply addressed the concern of potential sexual abuse happening in mixed saunas - on my watch, there were exactly zero instances of any inappropriate behavior. If this doesn't help - so be it, separate options never went anywhere. Enjoy what brings you comfort and safety.
