How would I be perceived at a gay sauna/advice

Hello I have no idea if this is the right subreddit to say this, but I’ve never been to a gay sauna before but I know theres a few in my area. Whats the rules/etiquette? and what should I expect? I’m 19m asian, 5”3, 110lbs and younger looking, and i’m wondering how I would be perceived or what would happen as I’m anxious how everything would be played out.
