I am one of those that have an uncontrollable navel (bellybutton) fetish. I don't know how to explain it, but women's navel turn me on so much. Maybe it's because being a first generation US-born Indian I guess? In Indian culture, young to middle-age females (even little girls) consider it a graceful gesture to show off their navel (like a badge of honor), and their fashion dresses are purposely designed to leave it exposed, indeed exploited, in view of the public. Some dresses leave just the navel exposed, but many expose the whole midriff. Anyway, seeing anyone fingering, tickling, or licking the navel is enough to drive me crazy. To me, it is the most under-appreciated part of the female body. I even think it's even sexier while the woman is pregnant. And of you females think the same about the male navel?
