Unless you're weird about it, it's one of the most harmless kinks you can have. Every time I'm with a prospective partner, and I'm like, "I have a thing", you can see them tense up and wait for you to drop the bomb that you're, like, an adult baby or worse. a furry*. Then you say "I like tickling" and wihout fail the response is always, "is that all?"
And because it's such a harmless kink, I've been able to indulge in it with friends or even people I'm not super close with. It's crazy, women who otherwise would never be into you will happily send you pictures of their feet knowing full well you're diggin' it.
