And if you read all the posts you'd know that I said ticklishness can change down the road of your life...it is not a set-in-stone-thing like eye color! So I don't think it's genetic, especially since self-control is a big part of being ticklish as well. A lot of psychology comes into the picture.
I've heard a lot of people who say that being ticklish is partially psychological. Would you mind explaining how this is so? I find this very fascinating, to say the least.
As for me, my mother use to be very ticklish when younger, but she hated it. She lost her ticklishness in her teens and still isn't ticklish. She was never into it. I can't say I know anything about my biological father, however, because I never got to know him personally. He was in prison for the majority of my life, and based on the reasons for him being there, I'd rather not try to get to know him personally, either.
I believe that - IF ticklishness is genetic, which I am not sure whether or not it is - I take after my grandmother. She's very ticklish, and I'm sure she may still be. (
I wouldn't know/try it thought! She hates it! AND has a violent streak! One would most likely get hit.) Hell, I'm more like my grandmother than my mother, naturally. I take after her in the foods that she likes. I take after a little bit of her personality. I take after her ability to be very cutting in my writing. (I'm not too good with verbal communication, but when it comes to writing, I've wiped the floor with some people, and my grandmother is the same way.) I'm almost nothing like my mother. I'm like ... part of my grandmother and part of my father (or so my mother has told me, AND held against me).
I'm 19 now and still very, very ticklish. So much so to where I'm not - neurologically - sure how to handle it sometimes. But then again, I do have an sensory processing disorder, and I don't personally know of anyone in my family who would have it. All the people in my family that I do know are all neurotypicals, and being a non-NT can - in my experience - drastically effect ticklishness.
