Hello Stein,
Yes I'm very often do it in English sometimes in German. It depends on the women.
Thank your for the advice again, sometime I think that I don't know how to flirt good. :/
I mean I had a lot of dates in the past but never something works, maybe because this women are not so sure what I want and then they don't have a reason to see me again. I want to change it now in the way that you explain maybe I have than more success
