"I knew vaguely that a majority have a foreskin, and that if kept clean it wasn't an issue...". Replace 'a foreskin' with 'labia' and have a man say this and hear the cries about patriarchy and misogyny.
Similar to what ppl have said above, there is a trope (really a genre now) in hentai about young men or boys having their foreskin retract for the first time, usually as a prelude to sex. Consequently, there's a related sub-genre where someone is embarrassed/humiliated if theirs doesn't retract - or isn't aware that it can - and then someone shows/helps them and they are no longer a virgin.
This is also where the foreskin-forward = "false phimosis" meme developed.
