As everyone who knows me on this forum is aware.. I love womens feet.
As for what Mairead said about guy feet being gross.
I don't pay attention to guy feet, but.. I think part of the reason what she said is true, is that most guys simply don't take care of their feet. Girls go for pedicures, get callouses removed from their soles, if they have any, give their feet baths, etc. Most guys, except for taking a shower, don't give a rat's rump what their feet look like.
I don't pay too much attention to my own feet, but, this year a girl, cant remember who, told me I have nice feet for a guy. If I met a girl who was into worshipping guys feet, and wanted me to take good care of my feet, I of course would do so for her, just like I hope a girl would do for me.
