I expect that sexual compatibility is an important factor for most people when they choose a mate. I didn't see it mentioned in this article, unless it falls under the umbrella of similarity in general?

For a while, I dated a lady who had almost no sex drive. I was lucky if we were intimate twice a month. In many ways we were very similar - we shared our most important hobbies, sports, pass-times, as well as beliefs about the world. We enjoyed each others' company and felt comfortable together for the most part. But I felt constantly rejected by her, deprived of intimacy and closeness, and resentful at having celibacy imposed on me. The relationship did not last, no amount of positivity could overcome that. I've heard too many versions of this story to believe that sex isn't an important factor in choosing a mate.
