What is an instant turn on to you?

[Heavenly44]

Can be anything

Can't lie a six pack

[OldAndWornOut]

A little line of hairs running down their belly and disappearing into their jeans.

Big thighs.

Beards.

[TomBradysLeftKneecap]

The ability to stroke my arm in JUST the right way

OR just actually being Zac Efron. He would be able to get away with an inability to stroke my arm just right....

[Wincarnis]

Intelligence, competence, confidence, manliness. In a uniform.

[lasttangoinscunthorpe]

DP is a police officer. When he comes home from work in uniform with a short sleeved shirt on, forearms bare...

[StoppinBy]

A man who is much taller and stronger than me, who could over power me in a heartbeat if he wanted but wouldn't (except in bedroom games when requested ).

[VetiverAndLavender]

Shirts rolled up to just below the elbow

Yes! Surprised someone had already mentioned this!

Also self-confidence (without cockiness). Just a sense that he's competent and knows it.

And a good sense of humour and a charming smile...

[Seafog]

Competency....could be in sports, woodwork, research, painting...
Show me a man with super skills, and I'm hooked

[PolkadotGiraffe]

Kindness, intelligence, wit, lack of arrogance, being tall and strong, independence, insight and understanding about things and people and the ability to speak eloquently about things that matter so that we can have interesting conversations.

[akerman]

Good sense of humour.
Kindness.
My DH is the kindest man.

[Laserbird16]

DH I love it when he puts his hands behind his head and stretches. I get to appreciate his biceps, broad shoulders and general v-shape...quite alluring. Plus he smells great.

[PolkadotGiraffe]

I find uniforms really gross. Each to their own for sure!

[SupremeDreamz]

Can't lie a six pack

A six pack of Scrumpy Jack is hot.

[Mypathtriedtokillme]

“Don’t worry about dinner, already arranged,” as he finishes vacuuming the house while wearing the baby is asleep in the carrier?

[coronafiona]

Kindness, generosity and consideration

[CatAndHisKit]

Nice hands!
not too soft / too rough, no small neat hands (eww)

Eyes / the right kind of gaze into your eyes.

[Guineapigbridge]

A Scottish accent

[Worried234]

Scrubs.
Forearms.
Driving.

[sergeilavrov]

Strong woody smell. If he wasn’t so wonderful, I could replace DH with a decent candle.

Forearms and the shirt thing are thankfully not just me.

[Tezza1]

Being listened to actively and intently, as if I'm the most fascinating person in the world.

[yvanka]

Curly hair and nice shoulders. Lifting/opening things for me. Agree on changing gear, weirdly.

[PineconeOfDoom]

Strength, forearms and, yep, the back stroking. I guess it all adds up to feeling very safe and loved

[FixItUpChappie]

Arm sleeve tattoo on a lean muscled arm

[Graphista]

Lopsided smiles and "flaws" can't be doing with "perfect" but a simple additional "flaw" a small scar or unusual walk or way of speaking or whatever and I'm hooked, ex had a badly set broken nose - yes I'm weird

[hopingforonlychild]

Jewish.

I always thought there is something to the belief that Jewish men make excellent husbands. I met DH before I became Jewish and before I met him, thought most men I met were dire and not husband material at all. But then I became Jewish and met more Jewish men through DH and socialising... Have never met so many eligible men- smart, educated, good career, respects women, does chores, good looking, eloquent, sense of humour. On the r/s boards, people are always saying that they can't find good men but unfortunately I can't advise them to go to a Jewish singles event or synagogue or Friday night dinner :)

[waitrosetrollydolly]

For instant melt - A Good smile and nice teeth.
For a slow burn , I'd want to be noticing good values, heathy attitude to others, kindness and character strength in equal measure. Good smell and good sense of humour.
