Jason, I’ve only been once.
My advice: Definitely just go, once you’re thru the first door its very chilled & relaxed, I did not feel any pressure whatsoever.
First off, I got talking to some guys in the hot tub, was totally honest about it being my first time etc. Got shown around by one of them, has a great time, got sucked by 4 guys in the darkroom, then later fucked a couple of guys in one of the private rooms in a 3-way.
That was my experience, I’ll certainly be back next time I’m in Newcastle.
