Not sure of the name of the mod

[larrybush1976]

There was a mod I played a long time ago, it might be gone for all I know.

I remember the entrance was by Helgen. You get a succubus follower and quests to go around banging other creatures. Oh yeah, something about Dibella leads you to those quests or something. 

Any help is appreciated!

Thanks

You're probably thinking of Sexlab Beastess, entrance at helgen, start the quest by reading a book dumped in your inventory? Anyway it has the quests you described (Though I'm not sure abt the succubus follower)

There are SE ports, you can find them on Loverslab as well. Hope this helps!
