Bodily options

When we were children, we could not imagine what an orgasm would feel like. That is an emotion you can experience only if you have undergone several bodily changes. My question is, can there be other functions like that we can only perform if we reached an organic maturity. A new kind of feeling may surface, let's say if you somehow upgrade your lungs to process nitrogen.

actually studies have been done and they made children orgasm, even as young as 1 (what's that knock at my door)
