theyre sensitive cuz its important to protect them for reproduction (guess that one kinda backfired lol)
and i think we find it hot because its an intimate and important area
so if it was just any other part, probably wouldn’t be as fun. think about like if someone was whipping your arm, idk about you but that wouldn’t do anything for me personally. spankings tho are also fun and they dont have any special sensitivity so maybe thats just about it being an intimate or embarrassing place to get dommed 😋
The thing with spanking is there is a nerve that runs from the glutes to the tip of the penis and the clit in women. Striking this nerve will create immediate arousal.
