Honestly I don't have any signs really I'm not even joking when I say that most of the time when gals are interested in me I'm just sitting there casually reading the newspaper and ignoring em or not really paying much attention to them.
I smile the same at everyone, I smile at everyone my body language doesn't change at all, I talk to both men and women the same way, I literally act no different regardless of whether I like someone or not. I would say my only tell is in my eyes probably, or when I do my signature half smile/smirk, but only women who know me personally would know that but even then it's kind of hard to tell.
Now with women it varies but usually it's in the eyes the way they look at you, they smile more then usual, more open to talking to you or keeping a conversation going, and have more open body language, and may also make excuses to touch you in some inconspicuous way, or obvious way if they defiantly want you to get the hint, playing with their hair or something along those lines. Not as smooth I guess when they talk with you know you like they find it hard to find words to use to talk or they may even stutter.
Long stares. Small smiles. Cat calls... though less desirable. They keep checking you out for long periods of time. They look like they have something to say. They stop paying attention to things around them. They might stand a little straighter and try to appear a little more cooler and calmer in your presence. They notice when you enter the room.
I keep checking them out when they think they won't notice. When it comes to opening conversation, I'm more tongue-tied. I either have a gormless expression or am forcing a smile (probably looks creepy). My eyes light up. Sometimes there's movement down below (especially if their curves turn me on). I either treat them in a more caring (perhaps controllingly so) manner or it's clear I'm desperately making an effort to engage them.
Girls tend to look over a fair bit if they like me. They blush whenever I pay them a compliment or I make a sexual reference. Their eyes light up when I talk to them. Sometimes they get a bit tongue-tied.
All that said, I'm pretty unsuccessful with women. I was fairly successful for brief periods between the ages of 18 and 27. I must find out how I behaved differently and go with that.
If her eyes genuinely light up and I catch her gazing at X body part. If I say a joke that isn't all that funny and she bursts out laughing, when at best it deserved a chuckle. Finding excuses to touch me. Blushing. There's a lot more, but those are a few.
Going out of your way to say hi to someone is a good sign. Generally the tent in his pants when he looks at you is a dead giveaway. For me if I'm attracted to some one I go out of my way to say hi. To talk to them I tend to be a bit more concerned about them. I choose them over more long term friends. Etc.
Eye dilation, flushed skin, perpetually watering mouth, change in posture to better display your better qualities, person becomes more assertive, open displays of anxiety/excitement, flexing of the abdominals, and so on.
Facial features. Curves. Height (I love tall women). Long hair, definitely long hair. Skin color, as I am generally only into White girls. Occasionally I do see attractive (White) girls with a nice tan. It's the whole package, basically.
for me, i've noticed it's when they treat me a tad different than others. i dont know how to explain it, because it's so subtle, but like, the way they look at you or interact with u may not be as 'effortless' as it is with other girls. another one may be when he glances in ur direction occasionally.
for me, when i find someone attractive, ill be smiling more than usual lol. not excessively but i probably look stupid :P
Well when I first met my ex he couldn't take his eyes off of me. He maintained eye contact the whole time I was talking, also he looked at me as i walked across the room, he had a bit of a nervous laugh and was joking around with me. I kept looking at him too but got all embarrassed and went red haha.
For guys I think its staring. I remember walking to class and I looked up shortly and saw a dude talking to his friend when I looked up and when I walked by... i saw him staring at me... like an oh my god look lol * I did look really nice*
Like he stopped talking to his friend and everything.
Also I think when guys give you attention... this other guy would always try to flirt and give me things, hold doors open for me lol... i liked him too but he was moving and so was I so I decided not to pursue it.
not really sure what you mean but dilated pupils increased respiratory rate intense staring looking away after getting caught staring mirroring staring at lips looking the person up and down Licking lips fidgeting readjusting hair and clothes biting lips touching face or lips softening voice
People's pupils usually dilate when they see someone that they find attractive. Also, when you're talking to the hottie, his body will be facing you, i. e. his feet are pointed toward you and his torso is facing you. That shows that he's being open with you and giving you his full attention!
