"Anyone know of any bi saunas in leeds for a newbie also do you get judged on size"
I think most saunas are a similar size, it helps with the heat distribution.
Only idiots would judge you on size OP. The men are there for the same thing cock . At mine . I've seen small to massive at the one I use in Southampton. Go with a open mind and ask the owner's for a tour and they will help
