Any helpful hints ?

I have never been to a "gay spa" where you only wear a towel or nothing and I am thinking about going to hopefully meet a guy(s) with similar interests. There is not one that close and I do not want to make a long drive and have a bad experience. None of my local friends have ever been to one so they can't assist me with any info. I understand that there is some etiquette involved. I guess you could say that I am concerned that I may give a signal for something and not know it and then end up with a bad reputation as a tease. I welcome comments.
