Ladies, this question is mostly directed to you. I have been in and out of this hobby in various cities for nearly 30 years, and have recently come back to Texas to retire. During that time I have frequently asked my prospective companion if she is foot fetish friendly. I occasionally got a response of no, but never inquired further. So ladies, what do you think a guy wants when he mentions "foot fetish", and what would make you say no?
My version is simply to kiss and worship a lady's feet during our regular activities. I know there can be other extremes, but I don't know what you ladies experience as a regular foot fetish request or activity. Also, is being ticklish a simple enough reason to say no?
(I shouldn't have to say this, but please keep the responses positive, informative, and based on the subject of the question. I simply want to learn the ladies' side of things, and also help my fellow foot lovers learn as well.)

Thanks!
