To anyone reading this thread and who is curious about what the oepn shower situation is like:
Let me just start off by saying I have had LOTS of fun at YMCA gyms. The open shower concepts are amazing. I love that Y gyms across Canada have mostly stuck to open showers.
A few days ago, I had a workout at the YMCA (the west end one, on College) and had a great time. Things were slow to pick up, but I love the fact that so many men here (whether they're looking for 'fun' or not) are completely comfortable with walking around naked in the change room to/from the showers, steam room, sauna, and whirlpool.
Towards the end of my time that particular evening, there was a group of us 4 guys (all young and gym-fit) having a circle jerk in the steam room. Mutual sucking took place too. Had a lot of fun and am heading back.
As for GoodLife, yeah, some locations are pretty fun and cruisy (like John and Richmond), and some, in my experience (like Bloor and Park) are not bad for making eye contact with a guy in the steam room, and then sharing a shower stall for some fun. Happened to me more than once.
I find that for the YMCA and GoodLife gyms, it's usually the early evening or late afternoon hours that attract that most fun.
Want to give Adelaide a try, and see what they're like.
