Maybe when they finish they can add a Hardcore mode, like in Fallout; where you have to eat, sleep, and drink at regular intervals or suffer negative effects, and death is permanent.
There actually is a 'flexibility' perk; don't remember where you get it, but you can find it in the Save Editor. Dont think it has any actual impact or implications, though.
Keep your wang dimensions as follows:
Lenght; below 2 feet.
Width; below 4 inches.
Do this and you can keep you penile pillar at monolithic size and still plow every hole in the game without interference.
