But, if that it's... wait where are it's legs!

TL;DR

The question starts with the assumption and hesitation that the bottle opening is being related to the male, "junk". Continuing with the assumption that the rest of the bottle is a person, it raises the question where are the bottle's legs? If we continue to look at the anatomy of the bottle further interesting questions arise: often bottles come to a little nub at the bottom, in the case of the picture, the top of the head. I am curious as to what this could potentially relate to. It indeed to me looks to be a closed poop maker. If that is the case than this bottle, as relates to a person, is anatomically fucked. His pooper is on the top of his head and his "junk" is at it's base, which also happens to be completely upside down from the orientation of a normal bottle. I think i'll conclude here to say that this picture raises countless interesting question if one were to extrapolate the existence of a penis on a water bottle.
