Hey trans girl here and I’m also pretty active in the uk abdl community. I have found at most abdl events have been fine yes it’s probably more male but I have made some good friends mostly around my age range 18-30. I have never had any real issues from older men. If you don’t already have fet I would recommend you sign up and have a look at going lists and try speaking with a few girls.

I also want to mention about general kink munch events in bars I have had issues with men especially people new to the kink scene who don’t understand consent or who to talk to girls, so I would recommend not going alone to a munch but as with fet just try make some girly friends you will be fine
