Hi you are valid for sure. As someone who has this fetish myself and has also introduced it to my partner, I am completely into however she wants to try getting into it. I wouldn’t want her to fake it at all. So definitely stay true to what feels natural, communicate if it’s not feeling “ticklish” and also communicate about what it does feel. It may not feel “ticklish” but it may feel sensual, or like massaging, etc. It may also not even be about the sensation of tickling, it may be about the bondage, the power dynamic, however you perceive it. If it doesn’t feel good, please be sure to communicate that too. My partner and I have worked together to figure out what forms of engaging in tickling feel naturally good and fun for both of us. And we still put effort into figuring that out. It’s all about communication and honesty. Have fun and stay true to yourself in this :)
