But, the question asked in the 1st post is not a sex question.
Yeah, actually it is - to a woman.
My apologies, 'cause I'm not a woman either... but I've heard enough of them talk about this kind of topic that I have a pretty good idea of how they'd react.
Firstly, if a guy walked up to a woman and asked her this question, she will immediately assume it's a come-on. Why? Because A) he paid her a compliment ("nice feet"), and B) expressed an indirect interest in touching her - because otherwise he wouldn't have asked her that particular question.
Now, what happens? Let's toss "attractive" out of the equation, because "attractive" is relative; a guy can think he's hot stuff, but the woman has to agree. Otherwise, he's not attractive to her, no matter how lantern-jawed he may be. After all, she could be into squishy effeminate guys or something.
On second thought, no; let's not toss "attractive" out of the equation. If the guy is attractive
to her she might be more inclined to humor him, or react positively to his come-on. After all, it's a pretty well-documented fact that good-looking guys get away with a lot more shit than ugly guys. But, and here's the kicker; simply by asking that question he
may go from attractive to unattractive in her eyes, shooting himself in the foot before he even gets out of the gate, pardon the pun.
Anyway, in my experience, women get defensive when a complete stranger walks up to them and expresses a desire to touch them before they even know his name. Even if they "humor him" and answer the question, they're probably just making nice and hoping he'll go away, no matter how much they're smiling. Smiling is a tension defusing gesture (ref: any book on body language you care to read) that indicates "I am not a threat. Look, I'm deferring to you." that keeps the situation from escalating.
Is what I just typed indicative of all women, everywhere? No. Some may take it as a compliment, or even play along. But here's the thing; why are you asking? If it's just because you're one of the dozens of creepy ticklers who gets off on pointless "polls", great. Get your answer, go home, and jerk off to your heart's content. But, if you're asking her in the hopes of getting some action, know that the chances of that happening are almost exactly nil. She
will assume it's a come-on, and the conversation will probably be over very quickly. Even if it isn't, talk is probably all you'll get. At the risk of sounding sexist, a lot of them have no problem winding up a random guy to boost their own ego, but when it comes to delivering on that promise, she'll just go home to her boyfriend instead.
Actually, after pondering it for a bit longer (always happens after you hit Submit, don'tcha know) chances are, if she's into you and
all you want is a quick tickle, you may even get it - although most of the time it's because they cave to pressure pretty easily and do stuff they don't really want to do - but hey, you got what you wanted and moved on, so who cares? (That last bit may or may not be sarcasm. I'm still trying to decide, myself).
I guess what I'm trying to say is that I haven't ever personally known a woman on who it'd work... but I have seen other guys who'd be able to pull it off. They're not the norm, though (and by virtue of having to ask this question, you're not one of them); and usually I have women offering me their feet by the end of our first date. Although that's a bit different; I'm not a complete stranger by then.
Your best bet is to just be friendly, charming, not overly-focused, and let her decide the level of interaction she wants to take. Charging right in will probably get you zip.
