it is nice to know that someone else has these thoughts.
Personally I am having quite a time imagining myself using certain terms... Master for example sounds a bit like "Riff Raff" from Rocky Horror... and I look nothing like Tim Curry in drag (not that I've dressed in drag to compare, this is an educated guess)...

What bugged me in the beginning (as a dom) was calling my sub things like "Slut" etc. You get used to it when you see the grand reaction though...

I suppose in German you could try: " Mein Gebieter" ....

anyhow, as long as you got the rest right I guess you could call each other whatever you feel comfortable with...
