Inspired by this thread, what do you find incredibly sexy? For me it’s compassion, intelligence, a warm smile and hearty laugh. Captivating eyes are a huge turn on, be they early morning sky blue, chocolate pudding brown, or garden after rain green.
Ever the insomniac,
Abby
P.S. Ear and nose hair are turnoffs, please trim or pluck! (Don’t take offense, it’s a joke.) 
Upon review, I realize that in all likelyhood this has been done before. I just thought it seemed to go with the other thread.
Turn ons: Sailors, 'nuff said. (or any uniform for that matter).
Turn offs: excessive hair on any part of the body, most especially the back. And a screechy voice.
Yeah, there is also this thread, but I suppose it never hurts to have more threads about the sexual preferences of our fellow Dopers.
As I’ve mentioned before, my turn-ons are females with any of the following attributes/accessories: Asian, tall, baseball caps, punk, kimonos, long straight hair, small/medium breasts.
Denim is also sort of a turn-on for me. I don’t go wild over it, but I think it looks good on a lot of women.
I’m also turned on by the smell of mothballs, for reasons I’d rather not go into again.
–sublight.
Playing the guitar.
Now that’s sexy.
Can you sing as well?
Then take me. TAKE ME WHERE I STAND!
Intelligence.
Accents.
A sense of humor.
Great eyes, especially the type framed by thick dark lashes.
Dark, longish, thick hair. Gimme something to wrap my fingers in and tug on. rowl
Generously endowed women.
I also find bald men sexy. It’s the self confidence that goes with taking the plunge.
And, of course, finding me sexy makes you really sexy.

Ditto! Dang I wish I had said that first!

Maturity. I’d take a 40-yr old over a 20-yr old any day.
The way a woman carries herself, the way she walks.
Laughing.
Blushing.
-Dark hair
-Skinny - little muscle, no fat
-Forearms - I don’t know what it is… I like it when a guy can get his veins to pop out on his forearms - I’m strange
-Back of neck - it’s good when they don’t have their hair cut straight across in the back - I like that little V
-They MUST smell good
-Musical - especially guitar and voice…mmmm…
-Intelligent - don’t have to be a genius, but must be able to carry on a conversation
-Somewhat driven - doesn’t have to have his whole future planned out, but has to care about something and not just sit on the couch all day playing Playstation
-Humor - I’m easily amused, so it doesn’t take much to make me laugh. If the guy can’t make me laugh, then he has a problem.
-Not afraid of eye contact
Weird, Shallow, Gross - it must be jarbaby’s list:
Treasure Trails on nice, flat, muscley stomachs are sexy
Guys who can smoke and talk with the cigarette gripped between their lips are sexy. But not every guy can do this. It’s a talent and style that I can’t quite articulate. I only know two guys right now who can do it.
Crooked lips are sexy. Ken Olin has crooked lips, so does Titus Welliver and Till Lindemann. Yumsky.
Guys who wear rings are sexy.
Whispering is sexy
and Power is sexy.
German accents are sexy
Now pardon me while I go fan myself.

My little list:
[ul]
[li]Funnyness. Make me laugh and you’re more than halfway there. Especially a dry, cynical sense of humour.[/li][li]A well-shaped mouth - not too fleshy, not too thin. And good teeth.[/li][li]Straightforwardness. Don’t beat about the bush. Unless i tell you to.[/li][li]Self-confidence. Not arrogance, but if you’re comfortable with yourself I’m going to be more comfortable with you.[/li][li]A firm, rounded bottom. Mmmmmm… bottom.[/li][li]Initiating a kiss. Kiss me confidently and I’m yours.[/li][li]Teasing. Play with me ;)[/li][/ul]

Long cigarette holders.
Gymnasts who mastered Kiegel excercises.
Girls who know their shit when it comes to cars.
Clear blue or green eyes that look about a mile deep.
Someone who can bring the passion and sensitivity out
of the stoic shell I shield myself in.
Well, no wonder you hang out at the boards so often, Arden. I know how many men here find you sexy.
Hell, I’m not ashamed to admit I’m one of 'em. If I’d known that’d go towards making me sexy, I’d have checked here before posting to that other thread! 
And that leads into what I find sexy. Basically, enjoying sex is sexy. Being comfortable enough to let go and have fun. To be sensual, playful, seductive…
Looks wise, I’m not that picky. Women of all types have their interesting features. Example: I like long wavy hair, but short hair gives better access to a sensitive neckline.
However, I do go nuts for cutoff denim shorts. De shorter, de better.
A brain is nice.
A spine is nicer - I hate it when a guy lets me push him around. (Sadly, this happens alot).
Nice strong pair of hands.
Smell is top of the list as well. Ya gotta smell yummy…
And, of course, he has to laugh at my jokes, cus I’m frickin HILLARIOUS!
Al.
Accents. Virginian race car driver Elliott Sadler has the sexiest accent I have ever heard in my life (he says ‘mo’ for ‘more’! Could it be cuter?). Gunslinger has the second-sexiest accent (the way he says words that rhyme with “you” is especially adorable, somehow).
I love to learn, so I find teaching me things to be sexy. At least as long as you’re not being uppity about it. Like, again with Gunslinger, he’s teaching me about classic cars. This tends to go hand-in-hand with intelligence.
I’m a motor junkie, so of course I find mechanicky guys to be super-sexy. The smell of engine grease is the scent of happiness*.
Also, a sense of humor is an absolute MUST-HAVE. I am a very quirky, sarcastic, and strange person, so it takes a special kind of guy to appreciate my sense of humor, to laugh at me and make me laugh.
To get a little more shallow, I love dark hair, especially worn spiked. I dont like mustaches alone, nor do I like full beards, but goatees are sexy, and so is having just a touch of stubble. You know, more than a shadow but less than the deadly sandpaper effect. It’s a fine line.
Nice strong muscley forearms are a turn-on, too. I’ll stop there.
[sup]* Conversely, the smell of wasabi is the scent of unhappiness.[/sup]
