THis is all fine, as far as it goes, BUT...
Something my mother told me when I was very young was, "If you want to give someone something, you do it because YOU want to. If you expect something back, THAT'S NOT GIVING and you should keep whatever you intended to give them, because going after someone with any intention other than Love is going about it all wrong."
Same with "getting" into an "LTR" (which I think should be renamed "Loving Tender Relationship" to remind people that it's about being loving, not about "getting" someone so you don't have to be alone).
I found that when I was sweet and affectionate and warm, it drew guys to me and when they were also sweet and affectionate, getting to play with their feet was easy. It was when they wanted my "warmth" but didn't have much of their own to give back to me that the problems developed.
My point is: Don't MAKE nice to get something. DEVELOP kindness and you'll find you'll attract the kind of guys who are generous, emotionally speaking, and care about what makes you happy. THAT kind of guy may not understand your foot thing, but he'll be a hell of a lot more likely to want to drive you crazy with his feet than some selfish guy who only got into it because he wanted something from you. The selfish ones are only in it for themselves (ask ANY woman: they know better than anyone) and they'll go along with what you want - but not because they're inherently good. They just see "going along with you" as a means to an end. And I'm sorry, but that kind of human being didn't grow up in a happy environment. I can almost guarantee that if you start with being a truly loving person, you will find guys who want to please you -- and that means playing with their feet!
