WHAT?
If a man gains weight, and develops manboobs. is he now this gender?
How about developing gynecomastia? That suddenly make him no longer male?
A combination of features does not create a distinct third, IT'S A COMBINATION.
In fact, men already have nipples and areola like women, and the clitoris looks just like a small p**is for a reason. Congrats, you just proved there are not 2, not 3., but only 1 gender.
