Went Sweatbox a handful of times a few months back..and it was an interesting experience each time.
Open to going again, but I guess these are my observations. (I can be kinda nuanced on some topics, hopefully it's of value to...someone lol)
The Good
The Layout: the infamous "maze" design of the sauna/steam areas, as well as the whole ground floor cabin, cinema etc areas is really cool. It kinda gives the feel of there always being **something** to discover. Be that action taking place or new people who arrived while you were elsewhere. It's not one-note. In one visit there's potential to cruise the steam rooms, chill in the cinema areas, have private fun in more secluded spaces, or literally just sit down if you so choose.
Having been to a few similar places in a kind of "dip my toe in" capacity, I think Sweatbox has most beat in this regard. There's a lot to do, a constant flow of people coming and going, and thus the time kinda flies even during lengthier stays.
The Clientele (Part 1): definitely leans slightly younger than some of the other spots and more diverse too. Probably 25-45 in age and and pretty much most races felt represented. And not just in the "token" way, but lots of Black, Mixed, South Asian, East Asian, Arab, and of course White guys too. Very "London" in that regard and welcomely so.
(In somewhat of a random sidebar, I don't think I've seen so many cut guys at the same time in the same place in the UK lol. As a POC cut American who now lives in the UK, cut-ness or the lackthereof is something I tend to notice. So, while I personally am equal opportunities when it comes cut/uncut, I guess this further points to the racial/diversity of the guys who come to SB).
The Staff: Very nice! Respectful and kinda take any sort of initial awkwardness away. We're all there for whatever we're there for and in many ways they set the tone for easing into it all.
Cleanliness: it was way cleaner than I was bracing for. Staff were often around making sure of it.
The Hmm
The Clientele (Part 2): In attracting a younger, perhaps more conventionally "attractive" crowd (cute faces, muscle bods), a slight drawback IMO is that two main vibes prevail (in comparison to some of the spots more frequented by older guys):
1) "less talking, more fucking" | Basically, a real-life congregation of many guys who more than likely are not out, exploring their bottled up desires before going back to their norm. Slight conjecture, but I really got that sense. With that, the upside is that you're probably likely to see (and get down with) a lot of "never would have thought they were into guys" type guys there. But the practicalities are that the most you'll get out of most of them before/after the action is a nod. Even the most basic of convos (e.g. your standard "hello") and you get the sense that you're asking "too much".
It's, of course, a cruising spot, so tbh there's a degree of "we all know why we're here" to it all. But the irony is that I'm probably nearer the venue's sweet-spot age and dare I say its aesthetic target demographic and can say with certainty that this is one thing some of the alternative places with older, more-seasoned clientele have over SB. I guess that's a pretty long-winded way of saying that people elsewhere seem...nicer lol. More approachable for sure.
Maybe not a biggie to those just looking for the hot guy for the night, but IMO a hot guy with a nice vibe is the ideal combo.
2) lots of people, lots of eye-balling, but not "as" much action as you'd think. I can't tell if there's a shyness (see: age, "DL" point above), but it was way more common to - as others have said - see people walking around and around like the crystal maze...for hours lol. Or glued to the wall. Or just staring. Or tugging at their rock hard dicks seemingly to entice the person in front of them only to shoo that same person away should they reach over. It really was something to behold lol.
So, there's definitely a heightened voyeuristic, exhibitionist, and cautiously curious vibe that runs adjacent to the regular/expected cruising spot activity. Because of this, it's probably not as chaotic or filthy as the places where they are fucking in every available corner (a good thing). But sometimes (and it really depends on the day/time), you can get the sense of "what's the point in coming - for hours on end at that - if you don't actually plan to...cum?" lol.
3) Race: Now, this may fly over the heads of most. But I really (really!) would love to hear from anyone who "gets" it, has experienced it, so on and so forth. As in, my DMs are open lol.
As a POC, I'm open to all races but have a slight preference for other POCs. What has been quite the revelation at SB (and I don't know why because it's a prevalent "issue" in general) is how many other POCs literally would only engage with White guys. I'm talking not even make eye contact with POCs. Yet, you turn a corner (again, a maze lol), and boom there they were with their White guy doing all the things.
Attraction is obviously subjective, it's also a place of freedom to do as you choose, and I'm personally very secure in self to not feel a way-way. But it was kind of an unavoidable fact that played out the handful of times I went, so it definitely wasn't an imagined thing.
Maybe self explanatory and/or maybe too complex to unpack here, but by contrast I don't have this experience at smaller places that are ironically less diverse. If anything, there was more magnetic pull from one POC to the other at those spots. So, yeah, was deffo a bit weird for so many fine POC guys at SB almost go out of their way (it seemed) to veer away from home base (I'm actually not even talking about with me, but moreso watching them do it to others). Deffo felt like a "do we need to call Dr Umar?" moment IYKYK lol.
In all seriousness, it's a really awks thing to watch/experience and something I imagine only fellow POCs "get" in fullness. Seeing so many hot POCs in 4K, who like guys too (thus eliminating the annoying guess-work we have to navigate in "real life")...only for them to be shopping exclusively White is definitely...something.
Last Thing...
As someone not seeking sex from such places, it'd be great if they embraced themes. E.g. bate bud slots, anything goes slots etc.
For instance, jerk buds is what I'm mainly into (and my upper limit of action). So, there's nothing worse than connecting with a hot guy, finding privacy, only for you both to scope out what the other wants in the moment realtime. Sometimes, you want the same thing and it's great. Other times, one wants more than the other and it gets...awkward...or flat...or both.
This was way longer than intended lol, but I do overall think it's a pretty cool spot and should be checked out if even to satisfy surface curiosity. It's kinda tamer than I was bracing for (which I found to be a good thing). Plus, there's a chance a bunch of the above may not apply on your visit or maybe even works for you lol.
