Why do humans adore the stomach...the belly... the navel piercing?

The female midsetion has always been seen as a symbol of femininity and attraction in women. Particularly, the navel and adding jewelry to it only enhances its appeal. Or ruins, depending on who you ask.

I like nipple piercings more. Don't ask me why.

Cause people seem to wanna have more holes in them

I think that's only you.

Why do some adore female breasts and/or butts? Or female legs? Why not adore female abdomen and navel? Heck I adore particular female entire bodies! Why do we like to kiss on the lips?

I don't need an answer for any of these.
