Brave girl
Seems like Dutch women still are a bit braver than Belgium women.
In my personal experience, my ex-gf and wife were/are no prudes neither.
They would go topless/naked if they had the chance ... however, usually only when nobody is around that recognize them (so mostly on holiday or trips away)
Only few times they have been topless/naked with people around they know, but in all those case more women were topless/naked, so they didn't want to be the ones who chickened out. But always a great turn on when they shed their clothes in public.
