I think there is an anime you should watch called loveless. Its set in an alternate reality where people have cat ears and tails. But when they loose they're virginity they loose they're cat parts. In the anime there is a school teacher about 25 years old who still has her cat ears. She gets teased for still being a virgin at her age. But as the story progresses she becomes more self assured and confident. And learns to like herself just the way she is
