I agree that genitals is the main sexes that exist between both genders but you'll agree with me that, it takes more than just genitals to belong to either side. Being a man, you've got your structure and also how you think to deal with. That a woman goes to the gem doesn't make her muscular equal with man and that men run transgender surgery to participate in a feminine category sport doesn't make the game a fair game. It's very much going to be unequal and the game won't be fair. It's not a good idea at all.
