Given feet are the most common fetish in the world, I'd hate to think what's going to happen when it dawns on some people ITT that a) chances are they'll date people with a foot fetish at some point in their life and b) chances are they'll date people with (much) weirder fetishes too.
Not a feet guy in a big way myself though.
Kissing is fine. Licking is a no.
It's nothing something that I want, it doesn't turn me on, but if my partner enjoys doing that to me then I'll be open to it.
I honestly wouldn't mind it but I'm extremely ticklish on the feet so I might end up kicking if I get licked there.
I think you lay off whatever you just had mate...
