About this mod Stand Alone Sexual Traits (SAST) is a stand alone mod for Crusader Kings 2. It has no DLC requirements.   What is this mod? I've seen requests in the past - and just recently again, where someone asked whether there was a stand alone mod that added physical sex traits (tits, dicks, etc.). The mods that do (Christianity and Dark World) include content that might be outside of a player's current interest, yet they're still interested in the physical traits.
