Psychology Doctor Lillypad is an earth mare who wrote the series of books "The Reproductive systems and mating rituals of sentient species". A very in-depth research of the sexual anatomy and habits of several species that roam Equestria.
She proclaimed herself as "Equestria's first sexologist" and now tries to help creatures with their relationship, sexual health and identity issues. "Try" being the key word, mostly because being the first hardly means being the best.
"Sex is disgusting, dirty, dangerous, mundane, corrupting, unpleasant, sweaty, tiring, lovely, great, delightful, unique, breathtaking, kinky, intimate, orgasmic, pleasurable, and with Celestia as my witness...
It's also extremely funny."
-Dr. Lillypad
