Yeah, going for the waist at that point would get a shriek even if you managed not to tickle me, and not in a good way. I don't care if you look like Sean Maher.
I think you misunderstand cousin_it's reference to "physical attractiveness". He's filtering not for whether you think he's good-looking, he's filtering by whether you are physically attracted to him at that moment in time, and open to the possibility of doing something about it, preferably as soon as possible. (This doesn't necessarily mean sex, btw, just being physically companionable and open to exploring the chemistry further.)
Anyway, if you're someone who's aversive to being touched by strangers, this will obviously filter you out.
I'll be honest here -- girls kino-ing me (i.e. touching to show interest in this way) used to freak me the fuck out. I wouldn't shriek, but I would definitely respond in a negative, abused-cat kind of way.
And I used to rationalize this response as being not just different but better and more right(eous) somehow than the dog way of doing things.
Nowadays, though, I realize that it's irrational to pretend I'm going to change everybody into cats or even that it's necessarily a good idea! (If everyone's a cat, who's going to do the stroking?)
So, while a stranger rubbing me the wrong way might make my hair stand on end, I have learned not to hiss, scratch, or run when I'm pawed by a dog person of whichever sex. Tolerating the discomfort or politely disengaging or explaining my issues with touch produces a better long-term result than just freaking out.
I've endured a fair number of lectures from my parents about how it's rude to freak out when strangers touch me. Here is why I go on doing it anyway:
It is always startling. I do not expect strangers to touch me, and I can't read them well enough to come to expect it when it's going to happen. This gives me little opportunity to prepare a response.
It often sets off sensory issues. I can tolerate accidental, very brief incursions into these issues by people who know about them and will stop instantly if they hear the relevant word, but anything prolo
Followup to: Do you have High-Functioning Asperger's Syndrome?
LW reader Madbadger uses the metaphor of a GPU and a CPU in a desktop system to think about people with Asperger's Syndrome: general intelligence is like a CPU, being universal but only mediocre at any particular task, whereas the "social coprocessor" brainware in a Neurotypical brain is like a GPU: highly specialized but great at what it does. Neurotypical people are like computers with measly Pentium IV processors, but expensive Radeon HD 4890 GPUs. A High-functioning AS person is an Intel Core i7 Extreme Edition - with on-board graphics!
This analogy also covers the spectrum view of social/empathic abilities, you can think about having a weaker social coprocessor than average if you have some of the tendencies of AS but not others. You can even think of your score on the AQ Test as being like the Tom's Hardware Rating of your Coprocessor. (Lower numbers are better!).
If you lack that powerful social coprocessor, what can you do? Well, you'll have to run your social interactions "in software", i.e. explicitly reason through the complex human social game that most people play without ever really understanding. There are several tricks that a High-functioning AS person can use in this situation:
