Why do people keep bringing such topics up? Well, I cannot speak for everyone but I can speak for myself.
1) How did I get this way? Is it nature or nurture?
2) Statistically speaking, the chances of 3 women in one group all not being ticklish is unusual. Did that fuel why I prefer women who are ticklish? Because female family members were not?
I remember as a 4 or 5 year old, the only females around were those women. At the time, I didn’t see it as inherently sexual. Because I was 4 or 5. I didn’t even know what sex was! Decades later, I still do not see it as sexual or sexually arousing.
That’s why this is called “Tickling Discussion” isn’t it?
(Also, it wasn’t until I was 18 and bought my first copy of “Licking and Tickling” did I realize I had a tickling fetish. Up until that magazine, I thought it was strictly a foot fetish, and feet just happened to be ticklish.)
