I have a foot fetish, only for womens feet but, the smellier they are the more I get turned on. I also like them to be slightly dirty and a little rough on the heels. sometimes I have trouble getting aroused unless I can suck a toe or lick the soles of my girlfriends feet. I know that foot fetishes are more common than people will admit but, is it normal that sometimes I need to have some "foot time" to get aroused especially considering I get turned on more if her feet are a little nasty? By nasty I mean sweaty, dirty etc. not ugly, I don't like ugly feet.
