That profile is very much how datingbuzz works (they are dominant in SA and most other sites are just reskins of them using the same database). I'm don't think that type of matching really works, didn't for me when I tried it years ago (that's when I wrote my dating optimiser app, but that's another story).
Really? I have no idea about those sites - I suppose chemistry is a thing of its own. I've ended up in relationships with people I never thought I would before. So you are right.
What I can say though. Is Ragnar is perfect in every way
Just go for it.
