I legit think that in depth butthole studies would be more beneficial to humanity than gender studies. Not proctology. I mean only focusing on the butthole.
Why is there hair? How to less / remove?
Best way to clean (most effective, cheapest, portable way)
How far can it stretch before tearing (for constipated and anal sex people)
Possible studies of use as unique ID (like fingerprint)
Does circumference correlate with anything? Number of lines in pucker? Etc.
You see there could be legit uses / results from butthole studies. Gender studies? Yeah, now we have fat guys with beards in the women's restrooms.
If the butthole reader on my phone works better than the fingerprint reader, I would totally us it every day.
