PERSONALLY I DON'T think there is anything dirty about kissing women's feet :O
Curious that you equate sexual with dirty. What does that tell us?
social conventions mostly... but if done with some style...kissing a hand can be very sensual.
Hands aren't usually covered, also kissing a hand is an accepted custom. Kissing feet isn't....unless you're a catholic priest.
If somebody kissed my feet, I'd be turned off. There goes your theory.
If you get to that point, it is all sexu*al.
Just dont kiss her ***.. it makes you her slave
Because feet are funny looking and smelly, just like other women's "parts", so kissing these areas are "sexy" because if we don't consider them sexy, then it would just be jank<br />
I dunno :)
Feet are covered, Hand is not
