My mate went to a Slosh event a couple of weeks ago so there are very much still active
I clicked on the link and the homepage said something about 34 years and still going strong or something like that, and they mention they started in 1989, so if my maths is correct that takes us to 2023, so the site is being updated
I don't know too much else as I'm not a member myself
Thanks for the updates! Glad its still going. I saw the "34 years and still going" part, but was not sure since the newsletter on the website had a date of 2010 and most of the DVDs said "unavailable." I hope to make it to the UK soon and would love to be initiated.
I went to one event last year, and I should be at the upcoming York one. Regarding inclusivity, I think to some extent it is what it is. Like a lot of fetish groups it was set up by men who are into men, just making the kind of events they wanted to see. Obviously I don't know what exactly they said to you, but I'd hope the issue is not so much about being trans, as being a woman applying to a gathering of gay and bi men. I prefer to see kink groups being all-genders, and if I was involved in starting something new today I'd want it to be that way. But I can see how some of the long running old-school gay spaces came about, and might be slower to change.
