38
What is the rooting reflex?
The ability for a baby to move towards the nipple when they have sensation near their mouth.
39
What is the G-Spot?
The Grafenberg Spot A location in the anterior wall, roughly a 1.5 inches in (feels like roof of the mouth/ soft pallet) That is highly sensitive to touch and stimulation.

What is the Penis?
The male organ of sexual intercourse. It contains the opening through which semen and urine pass. Contains 3 cinders that allow it to become erect.
