There is one already... Catholic!
you mean the monogamous, strict no devians religion? I guess theres the thing about every sperm being sacred and having more bloodly children that they can't afford to bloody feed, but i was thinking more like a cult that worships the act itself that you can turn into the greatest religion ever concieved.
You got me... I was being an asshole! Sorry.
The religion I was alluding to is the Yellow Queen. references can be found through Juno's storeline.
The religion was a cult with sex worship and rituals. Currently has ties to the Catholics and the Abby.
I really like this storeline and hopely there is more of the same to follow.
