My current significant other was abused by tickling as a child. His brother would try to humiliate and dominate him by tickling him till he wet himself. Now, I'm more of a ler than a lee, but I could never tickle someone for my own sexual and emotional gratification who had such bad associations with tickling. Fortunately, I am hopelessly ticklish, even when I really wish I weren't 🙂 so it's become a part of our relationship by default. We've only been together a few months, but I suppose if our relationship got to that point I'd marry him, but since tickling is such a negative thing for him I doubt I'd ever tell him about my interest. I'm afraid it would make me seem cruel, considering what he's gone through.
