California here, it all starts with eye contact. Usually in the locker room area or in the shower area. After that, its gentle strokes of his or your cock. Then it's off to the steam room or sauna. If he follows you, then you're half way there.
My first gay experience happen that way, I had no ideal this older man was into me, I had no intentions or thoughts of sex. He kept following me, creepy and weird. I thought he'd left and so I ended up in the steam room. As I was laying on my back I heard the door open, it was him. I didn't know what to do so i just stayed laying down. He stood up and started talking about the gym and how nice it was. I ignored him, that when he got closer and removed his towel. His cock was fat and hard, I was mesmerized. I had never been in this situation before, but I liked it. I sucked his cock and my dick was throbbing hard. Not sure how it all happend, but two other guys came into the steamroom and were behind me. They were stroking my cock and fingering my asshole, massaging my prostate. As soon as the first guy shot his load all over my face the next guy walked over and shot his load on my face. As I turned to look at the guy behind me, he shot his load all over my ass and back. I shot my load high and far moments later.
