It's all about context. What do you hope to achieve by incorporating tickling into your radio show? Given your biased position on the topic (You like tickling more than the average person.), I think it'd be VERY difficult to incorporate it in a way that didn't display some form of endorsement of something people view as a sexual fetish, and can probably get your show yanked for violation of the terms of service. Whoever you're going through has to cover their butts legally, and odds are, if something smells fishy, it's probably fish, and will be treated like fish, even if the fish happens to look different from other fish. They'd probably yank it to protect themselves. The simple fact is, people fap to this stuff. I don't know if YOU do, or if tickling is just something you "really like" without the sexuality attached, but many people register here because tickling SEXUALLY AROUSES them. If I were you, I wouldn't try to dance around the terms of your agreement, thinking, "Well, technically it's not pornography."
Your association with this crowd will not help you in an argument with a company about why your show got pulled because of its content. I don't know what you plan to do, but you're reaching into some gray areas.
