That's the joke. Saying "I want to fuck a virgin" realistically automatically becomes "I want to fuck a pre-tween" in this climate, sadly.
This sounds like jew-adjacent degeneracy.
LOL, how many cucks still buy that?
Believing "oh, I broke my hymen doing lunges for track and field" is giga-tier cope that guys try to believe when their wives tell them they are virgins but don't bleed on their wedding nights.
Moving the knees further apart would traction the skin in the perineum but the hymen is too deep in the vagina for that to be significant enough to tear it.
I'm pretty skeptical of the "I did it riding a horse" unless they somehow seriously fucked up and fell forward onto the "horn" of the saddle, and even then, what the fuck are they doing, riding it naked or in just thin panties or something? Proper riding is done in thick pants and if a girl wants to protect her hymen on the occasion of getting bucked forward onto the saddle-horn, she should wear a cup.
Tampons are 5cm long
Hymens are 2cm inside so a tampon should make contact, but the question is how far the hymen can stretch without breaking.
This relates to my original post idea. I propose that if hymens are GRADUALLY stretched that like skin, they could just permanently lengthen without actually tearing and bleeding.
To prevent her from bleeding and feeling pain because I am a gentleman and not a jewish vampire.
