I always do a double take when I read such statistics. How can they possibly add up? Are gen Z men considered particularly undesirable leading to lots of relationships with large age gaps? Is there a ridiculously large overhang of gay women (over men)? Is there a huge number of men with multiple partners?
These gender disparities are difficult enough to believe when they come to sexual relations, it gets even harder when talking about relationships.
I guess what I'm saying is: I don't believe those numbers as stated and would be interested in an explanation or at least a source.
