Does this pose problems for anyone? Well, even in 2018, it's still a big problem in many places.  Anyway, though, despite the problems, I see a lot of it about.

I'm Australian and my husband is American - two fairly similar countries you'd think, but there are still plenty of things that we argue about that are different! It can definitely pose some problems I think, because of what you've grown up accepting as normal -- so I try and bear that in mind. Every couple faces some challenges, whether it's different cultures, races, religions, even different hobbies can sometimes bring about arguments. As long as you're both on the same path overall I think it's all okay in the end.

I had a non-sexual friendship with a guy from England once and it worked awesome.  I mean, there was differences, but they didn't get in the way.  Anyway, I assume if this scenario can happen, then the same can happen with a female.
