You know that the average male is 7-9% taller than the average female right ?
This of course depends slightly on race, and to a bigger extent on environment (the worse living conditions are the smaller the actual difference).
And not all man are taller than all woman, neither in real life nor in the game. Three of the male body-types are smaller than the biggest female in game.
Not to mention that the problem is not who is taller/fatter/ whatever but that there are differences in body type that need to be addressed in any scene that involves touching.
Why does any of that need to be addressed? Is there some scene where a smaller character makes out with a taller one, and so gets kissed on the head instead of the lips?
If not, I don't see the problem.
Also, averages and majority are just that. Doesn't mean there aren't exceptions.
