Everyone is different. Some men have low libido, some women have high libido. Some people are unpleasant, some people are lovely. It's dangerous to generalize from our own experiences because they're non-random (we do, after all, select our partners even if we're not conscious of the reasons why we make these selections). In general I'd say you're probably right insofar as it's much more difficult for a woman with a high libido to find a consistently satisfying relationship, but then again... it's difficult for everyone to find a consistently satisfying relationship. There are countless reasons why relationships don't go well. Singling out libido seems arbitrary.
