Sex Ed: The Erotic RPG is an adult 3D animated dating sim and sandbox RPG made by Red Mango in Unity. You play a newly created college student who accepts an offer to spend the summer with best friend Emily in her university apartment. The game emphasizes player choice and reactivity in an explorable college town, letting you decide relationships, work, and classes while shaping future options.
The current build is v0.3, released August 14, 2025, with development ongoing. It runs on Windows and Mac in English and is uncensored. The latest update adds new story content for Nicole and Kim, ten quests, nine erotic scenes, and access to a mall area. It also lets you buy and change outfits, delete saves, and skip the opening tutorial after character creation. Some scene timing and attraction icons were changed.
Developer's description
Your best friend Emily has invited you to live with her for the summer at her university apartment. Without the funds to move out on your own and knowing this might be your only chance to have the full college experience, you eagerly accept Emily's offer. What adventures await you? What unforgettable connections will you make?
Spoiler
Sex Ed is all about
immersion, reactivity, and player choice
in an explorable 3D college town. You can role-play as the best version of yourself or someone else entirely and live out your fantasies in a
nonlinear sandbox where every choice is yours to make.
At the start of the game you'll create a new college student, and then it will be up to you to decide who to date, where to work, and when to attend class. Your choices will influence your future opportunities and options. With Sex Ed, I'm building the kind of adult game I've always wanted to play.
