The amount of toxic masculinity brain rot required before you willingly go for such an invasive procedure is inconceivable to me.
The writer says there's some indication it may literally be a psychiatric condition along the lines of body dysmorphia, and that most people who go through with it are at least average sized but unhealthily preoccupied with their member, consistently reporting feelings of shame and helplessness.
She also says that supposedly the consensus on the evolution of genital size has been quietly moving away from assumptions about giving an edge with inseminatory success and towards them being just for show, as apparently male primates do tend to involve their genitals in threat displays. Which is to say, maybe for some people it's just unusual wiring that manifests as penis related existential angst.
Still, it doesn't mention the extent to which the above is just evo-psych enthusiasts idly theorizing, or if field testing actually showed it's possible to win a showdown with a gorilla by dropping trou and windmilling.
And then there's also the guy who had the procedure done and is super happy about it, except he's now looking at options for enlarging his wife's vaginal canal and entrance as she's been having a rough time of it, and who I'm sure would be found out to be the walking and talking personification of toxic masculinity if you were to give him the time of day.
