Firstly: Please note my avatar - new member, never saw this thread, first one I laid eyes on. Spooky. Or not.
Indicates my opinion that Keira's tummy is the most delicious thing I'll never get hold of.
Also, I'd have to agree that English doesn't have an attractive word for this region of our bodies. I think that 'navel' has a nice ring to it however.
No pun intended.
