Completing an NPC's quest will add them as a Lover. To get that sex the Dragonborn will need to build up a relationship with various (vanilla Skyrim) NPCs by completing new Quests. So, needing sex is all just part of being the Dragonborn.
The plot hook is that whenever a Dragonborn kills a Dragon and absorbs that Dragon's Soul they become wild with sexual desire. This Mod attempts to incorporate sex into Skyrim in a lore-friendly(ish) and immersive way by adding a plot point to the main story line of the game which involves Sex. Neat! But maybe, just maybe, there's a small curse as well. it seems to be all upside huh? You get some shouts, people treat you special and you get to save Skyrim.
