For me it's confidence in a lady. Can't beat that.
Close second with how they shape their body during different positions etc..

 

An example.. Ass up when giving a blowjob! Great view for the male!

 

I'm not sure that this turns me on most, physically, but it really puts my head into it. My body usually follows my head. And that is seeing how much my partner is turned on and enjoying himself/herself. I don't think anything is as satisfying as satisfying the one you love. But if you are talking about a particular physical act during sex, not foreplay, then I think it might, maybe, possibly be having my boobs sucked and fondled, or just a lot of deep kissing. If you include foreplay, then it might still be my boobs, or kissing, or maybe oral sex, either giving or receiving. It isn't always the same. Sometimes I'm in the mood for one thing and at other times I might prefer something else.

 

It definitely depends on your mood like you say.
But a blowjob like the pic above will always change my mood back to that being my favourite!

You just can't beat it in my eyes!

Of course it depends on how good the female is at blowjobs. And how good her ass is.

 

The most turned on is when I role on top of you cowgirl style, my hands on your chest and my hips rocking about; your cock deep inside me, watching your face contort and grimace as you reach climax, the way your chest moves as you breath, the way your cock throbs, the way you grunt and cry for you deity in you hushed desperate tones ... all that is like an electric shock to me. Its one of the hottest parts of sex and the biggest sexual turn on to me.

 

I also agree. Cowgirl is great! If the girl is good!
Hard to find a confident female who really can ride these days But your right.. reverse cowgirl is a favourite of mine!

 

Having my nipples played with and a woman who really knows how to talk dirty...

 

She on her knees and me seening my dick slide in and out of her pussy. I can lean around and see her big tits dangling down and swaying back and forth, all the wile I have her cheeks spread and playing with her asshole with my thumbs.

 

I love licking, sucking a ladies clit and watching the excitement build in her face as she gets closer to an orgasm on my tongue....then when that moment happens and her pussy squeezes my tongue and her back arches......makes me want to cum at the same time but I hold off until she gives me a nice, slow, hot rimjob......then my back arches!

 

for me it's always been when i sink my cock in a girls sweet wet pussy!! the heat of it, and the tightness of it dammm i love that feeling, kissing her long and slow, kissing her boobs and looking in her eyes as i fuck her,and i love her smell to, her natural oder she has, her scent mmm love that too!!!

 

My first turn-on, after the foreplay is over and we are both READY is that first second when my head slips in, feeling her puckered opening sliding around and up it, then over the rim to grip my shaft. Then the sensations and her sounds as I penetrate and her gasp and grunt as I go fully home. Then as the mood takes and suits, grasping, squeezing, pulling her tits and nipples in time to my thrusts, riding high so my cock rubs against her clit and hearing the sounds that makes her make; seeing her face contort, hearing her moans and feeling her contractions along and around my cock, matching its throbbing as we both cum.
In doggie, slapping her arse as my cock is just in, then when its tingling pressing my belly hard against it as I thrust in, gripping hips or hair to aid the ride.
In cowgirl when she first slides along my cock's length, exciting her clit on its head until she's ready to lift up and fully take me, feeling her butt squash my balls while she grinds to orgasm, while I have full access to her tits, nipples and clit to do with as I please and can see her face as she cums.

 

Reading that alone was the biggest turn on. I'm wet

 

Honesty!!

Thinskin

 

Two things turn me on the most.

One is her reaction. Like others have posted, my partner's reactions to what I am doing to her excite me like almost nothing else. Her moans and groans, her hip movements, her muscle clenches, her holding me, her wrapping her legs around me, her stretching and grabbing the sheets all make me want to fuck her harder and deeper.

The other is what I feel. I like doing anal. When I gently push the head of my cock against her asshole, my anticipation of the pleasure to come hugely excites me. When she eventually relaxes and opens her asshole to my cock and I enter, the feeling is fantastic. Her groan as I enter her turns me very on! When I am deeper into her, I ask her to squeeze her ass muscles around my cock. That feeling is one of the most pleasurable to me in sex! It doesn't happen often, only 6 or 7 women in my lifetime, but it is absolutely fantastic when it does!

 

The biggest turn-on during sex will almost always be verbal and whispered in guilty tones. Visually it's her flesh itself, I can see my spunk on her skin before I've cum. Physically, my tongue is possibly more sensitive than my cock and depending on my mood, that could be anywhere...

 

The fact that I'm having sex.

 

true, but i like that she want to stuff her pussy

 

For me it's when tells me to cum in her with my big dick
