HA! NOT TICKLISH! Not ticklish, he says! My good man, you are talking to the KING of running into not ticklish women. My female best friend, the first girl I liked and almost dated, the first girl I ever slept with, the first girl I was absolutely crazy about borderline love, and most important of all, my oldest and best female friend (eho I have been trying to find a tickle spot for since high school... soooo demoralizing!!)
Sorry. Not really the question. YES to both! Though I find not ticklish at all a LOT MORE hopeless than "I hate tickling". If someone truly (and I say truly because sometimes under the hands of a professional or under the right circumstances someone might appear to be ticklish) isn't ticklish, it's a hopeless and demoralizing situation. Tickling is my main form of foreplay including tickling resistance games, etc. Nothing really turns me on and gets me in the mood (under the right circumstances) than that, so if someone isn't ticklish at all, that takes away a major form of foreplay for me.
As far as "I hate tickling" goes, that is more manageable. There are several possibilities here to work with. If you're dating a girl who is extremely ticklish, the possibility exists that if she knows you like it and it turns you on, she very well may allow you to do it and even adapt it in bedroom play. It's entirely possible that they have only ever known the annoyingly torturous side of tickling and not the flirty playful fun side.
For the purposes of this discussion though, I kind of feel like you're asking in regard to "I f***ing hate being tickled!" To the point where they get nasty and violent. I have known women like this. If they hate it to the point where they get nasty/violent, it can be just as much of a turn off as not being ticklish at all. Tough situations all around really
