European spandex/latex events around May and June

So I will be in Slovenia visiting family between May 29 and June 5. I am currently trying to figure out if I’ll be staying an extra week and a half before or after. I’m not sure which countries I’ll be visiting - my thought is to spend 2 or 3 days in maybe 2 or 3 countries just because I hate travelling and if I’m going to Europe, I’m only going once. Any suggestions to which countries have great gear scenes and any cool events around those visit dates. Would help give me an idea of which countries to go to and which events I could attend.
