Men, women… squck… anyone?
Women standing on tiptoes particularly if barefoot and wearing a short skirt.
Receiving an out of the blue vulgar SMS always cheers me up.
Guys in tweed jackets with leather patches on the elbows.
I dont know why, but watching women shift gears in a manual trasmission car, is damn sexy.
[sub]Wait, maybe I do know why…[/sub]
Well, the sexiest situation could take some complicated describing 
- so I’ll just mention something not overtly sexual that I do enjoy:
The view from behind of a woman in trousers (jeans, whatever) when she’s standing with her feet about a foot apart.
When a woman sits cross-legged, and the slit of her skirt along the side of her leg exposes the lace at the top of her stocking.
The side of a woman’s breast, at the point where the breast meets the torso. This is the most underrated part of a woman’s body, in my opinion.
Non-native French speakers speaking French. Especially when it’s sudden.
Well-dressed, clean-shaven men with a twinkle in their eye. Maybe with the jacket tossed over their shoulder just so.
Women wearing wifebeaters. And baseball caps with the ponytail sticking out the back.
On first reading, I thought the question was “What … do you find sexist?”, so the first couple responses didn’t make sense at all…
Situation: Stability and strength moves in sports–anything that involves slow, steady grace. I love watching Pilates, for example, and the slow parts of figure skating or dancing.
Outfit: Sexy Mrs. Santa Clause outfit, with the fur-trimmed miniskirt and fishnet stockings.
Words: umm… drawing a blank, here…
Gestures: see above re: situation.
I find it sexy when my husband is doing something that he is intense about, usually something athletic, playing golf, playing hockey, coaching.
Sexy.
The girls I most like to watch have a specific look: Thin (almost wiry), athletic, short hair, long cargo shorts, soccer shoes with no socks or ankle socks, t-shirt, hemp necklace, long hair (maybe dreadlocks) up in a careless ponytail, usually tan because they spend all their time outside.
That seems really specific, but there is a particular type of girl… I associate them with Colorado. The kind that both smoke and eat granola, you know? 
Situation, um, I like being slowly woken up with cuddling. Slowly. Too fast and I get irritable. If that doesn’t count, being alone in libraries, preferably after hours.
Outfit… Oooh… I’d say schoolgirls but that’s borderline sicko :eek: So I’d have to go with tap pants 9as in the lingerie, not the dance togs).
Words… I like hearing softly spoken Asian languages, particularly Japanese and Chinese. They could be telling me what the specials of the day are, but I’m all over those tones!
Gestures… Hrm… I like it when women look over their glasses and grin… Honest laughter is also good.
A warm, sudden smile from a woman gets me every time, even moreso if it’s back over her shoulder. One eye peeking out from long hair that has fallen forward over her face is good, too.
As to clothes, anything that shows off a woman’s tush is a good thing in my book, be it well-fitting jeans, a dress that clings just so, or what have you.
Situation: A woman doing an endurance sport well. Well put together women in coffee shops. Women strolling through a mall.
Outfit: Halter top or fitted t-shirt, perfectly fitted jeans (not floods!), high heeled sandals with well manicured toes.
Words: I like when a woman calls me “Baby” or “Lover”… as in “Come 'er, lover.” <wooo, shiver> I’m so there…
Gesture: A fake little pout. That come hither look.
But all that must be backed up by a sharp mind. Smart is very sexy.
Situation: One of the things that gets my blood racing the fastest is when I meet eyes with someone whom I think is attractive, and who obviously thinks I am too. That moment of contact.
Outfit: I already answered.
Words: The word Cheers! Or really anything said in any of the accents from the UK.
Gestures: When a guy pushes his hair back from his eyes, just so.
Ha! I completely forgot that that arousal trigger gained notoriety in gag form by such an outrageous pop-cultural icon! And I just sat here and unwittingly described that old bit verbatim.
Here’s examples, in no particular order:
So… women with bad eye sight? :dubious:
