Hi Sunny,
I am one of the (brand new in terms of forum membership) English speakers on here. When it comes to my little space, English is the more natural language for me. Things like diaper, onesie, coveralls, and spanking just push other buttons in me than saying Windel, Windelbody, Latzhose, and Po versohlen. Speaking English in little space makes me squirm and blush much more easily. Those English words saw a lot of use in past years.
People in the US seem to think that Germans are kinky by default. Fortunately, work and friends give me plenty of opportunities to speak English to prove them right by uttering lewd comments.
I just created my account on this forum today to look at the discussions regarding an ageplay event I will be attending. I have not done that sort of thing in a while for various reasons, but now I am really looking forward to attending one again.
A long time ago I (inter alia) went to a couple of SMJG meetings, but the folks back then were not very welcoming to ageplayers and focused more on the whips and chains side of things. There are, however, a number of ageplay gatherings in Germany and Europe at large. For example, "Hyttetur" (an AB/DL retreat) will be taking place in Denmark from August 18-25th and there is a diaper camp in Germany from September 13-16th.
There will be a few separate ageplay events at the Quälgeist in Berlin on the weekend of September 28-30th; 150+ participants are expected at those events, which probably makes it the biggest event in Germany. Friday is only for diapered boys whereas the events on Saturday and Sunday are for the whole ageplay community regardless of sex. There will also be a big ageplay event (Ageplay Freizeit) from November 1-5th in the Harz region, but I think you would have to get on the waiting list for that one. Some big events in the US such as US Littles and TeddyCon are also coming up. Sometime in December there is an AB/DL-themed Christmas party in Amsterdam.
As you can see there are plenty of events to choose from!
