A third nipple usually occurs somewhere on the chest, but not always. Brazilian researchers recently reported the first case of a nipple occurring on (wait for it) the bottom of the foot.
The case is that of a 22-year-old woman. Her foot nipple was fairly well developed with “well-formed nipple surrounded by areola and hair”. Dr. D.M. Conde and three colleagues from the Department of Gynecology and Obstetrics at the Hospital Estadual Sumare and the Universidade Estadual de Campinas in Sumara reported the case in May 2006 in Dermatology Online Journal.
I'm looking for photos of this one... I bet her feet are really ticklish!
*Titillating: from the Latin, titillare: to tickle
1. To stimulate by touching lightly; tickle.
2. To excite (another) pleasurably, superficially or erotically.
So yes, the "tit" in the word "titillate" DOES have a sort of double-entendre reference to nipples. That's why it's on this blog.
