I don't see a nub

Ty, anyone else think they see one?

I think I see a hint of a boy nub. Take a peek at mine if you can:)

I *think* there is a boyish nub on the second picture. Only prob is that baby is pretty arched. I would go 60-40 boy.

Not sure there is a nub, but if what I am looking at is a hint of a nub I am thinking boy

Boy

Ty everyone for your guesses? Anyone else see a nub?
