I’m late to this party, but I’m gonna go with “No” also on the grounds that I’ve got plenty of sex games already, CDDA isn’t a porn game. And, personally, despite several sleep deprived moments of what I thought would be hilarious editing, it’s a bad idea.
The Fallout Games (With one exception), The STALKER games, and I’m willing to bet others were post-apocalyptic (…only sorta in a few cases) RPGs that could have featured sexual content, but for the most part didn’t allow the player to partake in it. There were a handful of references, but with the exception of Fallout 2, there was no sexual interaction, regardless of your reasoning for it. (Even in Fallout 2, it was mostly a bad joke.)
On a related subject, I don’t feel the infrastructure for such a mod should be worked into the game. Because with just about everything in the game, once it’s in, it never leaves. The recipe for “Royal Beef” is still in even though it was made obsolete god knows how long ago. if we decide down the line that such functionality is a bad idea, it doesn’t come out because apparently there’s still some guy out there running a save from the first version after Cataclysm was forked into DDA.
