Hey, the nerves are hard to get over. But it’s really quite a relaxed environment.
Not sure you need to take any precaitions, but be aware that prolonged eye contact is usually I sign that you’re interested in somebody. A polite no thanks should be enough to send anybody on their way if you’re not interested. And be prepared for a few guys to brush against you as you pass touch your ass and maybe your dick through your towel
Any questions just ask
