I will clarify:

Well, it is originally so created by nature (god, creator, demiurg, flying pasta monster - it is necessary to emphasize) that if two want more than communicate, then their genitals must be OF DIFFERENT shape. The law only confirms that. Because it is nefigured.

Not more than communicating, but continuing, because only this is important to Mother Nature (God, LMM and even with them). And whoever there just touches - these beings are deeply fooled.
