I have something interesting to add to this: a girl turn from one side to then other and then back again...and in more ways than one...
An ex-girlfriend of mine was neutral to tickling when I first met her. As our relationship progressed, and I told her of my fetish, and we began to incorporate it into our sex activities, and soon, it seemed that getting tickled was turning her on. By the way, this girl was at least a 9.5 on the ticklish scale. It seemed to me that by giving her sensations of tickling and sexual pleasure at the same time, she would associate them and they would become synonymous...which is pretty much what the case was, very early in the relationship. I was overjoyed that I had finally found someone who could share in my desires.
However, I made two crucial mistakes, and the relationship (not as a direct result) began to disintegrate.
1) I tickled her way too often...I became tickle-greedy and only after she spoke up did I stop doing it so much. I have to say though, I loved this girl more than anything in the world, and I never meant any harm. I was oblivious to the fact that I was doing it too much, until she told me.
2) I was not good about seeing to her sexual needs. I only tickled her, for my own pleasure, and rarely engaged in any other foreplay. Once again, I was oblivious to this until much, much later; I never meant to be selfish. She never told me what she wanted (but I rarely asked), and I was clueless, so I never helped her out...
Eventually, she began to hate being tickled, but I think it was because she associated it with my desire for sex. In our relationship, however, sex was a sore issue, because she never wanted it, and I always did, and so we both felt guilty. It turned out that she was a lesbian, so we broke up and parted ways...
After having spent much time thinking over what went wrong, I came to the conclusion that her eventual dislike of tickling had absolutely nothing to do with the sensation itself. It was that she had come to hate sex, and everything related, so when I tickled her, she thought of it as me trying to initiate sex, and thus reacted negatively. Long story short...it's all psychological...
And here's another interesting bit...she is now in a relationship with a girl (who isn't into tickling) and doesn't seem to mind being tickled at all. I have observed this happen, and she has offered no protest.
I'm only 19, so I don't have much experience, but If I may give some advice to everybody else (based on my own personal life)- it is extremely important to be aware of these things: your lee's feelings about tickling, how much you tickle your lee, and most importantly: KEEP AN EYE OUT FOR WHAT ISN'T BEING SAID!!!! Communication is the most important factor in every relationship, and my ex and I didn't communicate enough about tickling (not to mention the fact that she liked vagina more than I did). So just keep a healthy open discussion about tickling, sex, and everything else.
Whoo......never told that story before....felt damn good though...
Now everybody can use me as a guide for what not to do 😀
