What to know what would be pretty sick? What if you could build "sex blueprints" so that you can place down a sex position anywhere in the game; so it's not just the barn where kobolds fuck. It would be a clipboard item, maybe with a crude drawing of kobolds fucking on the front perhaps? Could even require money to build the sex blueprints if the devs want an additional money sink, but I don't think that's an issue atm, but just a thought.
This of course would only be for sex positions that don't require furniture or unique terrain (the table, couch, and the one by the fridge for example).
Also some more giant kobold on smaller kobold sex positions would be nice
