I don't know about Europe in general, but my brick and mortar bank (one of the major banking chain in France with an agency in pretty much any city of over 5000 people) was perfectly fine with adult things being sold using one their group's online platform as long as I was ok with their elevated rates. I've seen lately that they're also responsible for payment processing on dorcel.com (the french porn group, adult content and toys). Dalenys ( https://www.dalenys.com/ https://www.dalenys.com/ ) -> natixis belgium -> natixis -> bpce group ( https://en.wikipedia.org/wiki/Groupe_BPCE https://en.wikipedia.org/wiki/Groupe_BPCE ) I've had awkward talk with them (mostly around the fact that I should not point out their parent group brand much near the adult content), but never in a million years would they tell me what color a dildo should be.
