If you come to think about it, they both seem similar. The guy (let's call him Joe) must have a difficult time interacting with a woman for him to never turn a date into a relationship and have sex. Joe might also be giving bad vibes of desperation.
In the female version, Martha has a hard time reading cues of men that aren't into marriage and kids or like her male counterpart, she might give bad vibes of desperation too.
It seems to be producing the same results. Both end up feeling like failures. Joe can't form intimate relationships at some point and Martha can't find a suitable partner interested in marriage and kids after a certain age (30+ years old for instance).
Come to think about it, if those Joe and Marha reunite (the forever lonely male and the woman unable to get a man to propose to her), due to their desperation and flaws, along with thinking they won't find anyone better... they might give each other what the other have been looking for. They both have something in common; they don't want to be alone in the end and think something is better than nothing.

There are definitely some similarities.
Women are generally the gatekeepers of sex, and most men want sex very badly (not that they're all "desperate" for it per se, but they nearly all want it).
Men are generally the gatekeepers of relationships/commitments, and most women want those things very badly.
So, yes, there is definitely some symmetry there. Obviously the smaller details are quite different, but from a big picture view, they have a lot in common.1
