“I suspect most men would suggest the reason for adopting the more spread posture in sitting would be the avoidance of testicular compression from the thigh muscles. The pelvic rotation goes some way to improve compression in both aspects,” Sutcliffe continued.
Sitting more expansively may also signal dominance and sexual attractiveness for males. Tanya Vacharkulksemsuk, a UC Berkeley post-doctorate researcher recently published studies that found spreading out legs and arms is more sexually attractive when males do it.
Men have smaller, narrower ischium bones, which means we need more stability, hence why we sit with our legs open.
Leg spreading
"The behaviour is based in ancient history and is rooted in being able to protect," she told the Daily Star. “When men want to be seen as both attractive and protective, they will often splay their legs or drape their arms around nearby objects, like a chair or stool."
When a man uses this legs-apart stance, it often signifies dominance, as it highlights the pelvic area. It allows men to highlight their masculinity and show solidarity as a team by all performing the same actions. So, if you want a confidence boost, or just to appear confident, use this stance.
An open posture and facial expression are also signals of attraction. Acting fidgety or nervous, or blushing and getting sweaty palms, is also a sign that someone is attracted to you. Casual physical contact and leaning in when you're speaking are also signs of interest.
Splaying legs and arms is actually a territorial display of dominance. In other words, when we make our body take up more physical space we are actually trying to claim it as our own and assert power. Men do this because men often feel the need to claim power in a room or assert dominance.
Paying attention to a man's body language clues can help you decipher whether he is interested. If a man likes you, he may sit facing you with his legs spread open. This indicates that he is open and receptive to you.
He might not touch back, but if he does, you've definitely got the green light. Men who are attracted to you might even engage in more touch. If a man actively tries to touch you during your interaction, it may mean he wants to get closer to you or close the distance between you two.
Specifically, expansiveness signals access to resources and dominance.” The results of the study suggest that people are more attracted to an expansive posture because it conveys both social dominance and openness.
Guys subconsciously default to this position when they relax because they feel more at ease with their essential organs out of harm's way. “You could think of the hand there like insurance against a friend who might give them a nut jab or a kid who accidentally hits a ball at them,” says Van Edwards.
Women: Guys will check out your chest and waist-to-hip ratio regardless of whether they see you as friend or partner. But they will look longer and more often at your face when they have romance on their mind. Men: If a woman seems focused on your face and chest, she sees romantic potential.
He is looking at your lips
If his gaze keeps slipping down to your lips while he's talking to you, it's a sign that he is admiring you, fantasising about you and might even want to start a stable, long-term relationship with you," says Madan.
Men prefer a woman who can stay calm and relaxed. Beauty is more than make-up and a fancy haircut. Men find women more attractive when they are neat and clean. Men find women who smell nice, who have clean hair and hydrated skin more attractive than a face perfectly covered in makeup.
He's Staring at You
If you notice he is making more eye contact with you or you catch a guy staring at you, he is probably attracted to you. He may be enthralled by your good looks and may be fantasizing about kissing you. Perhaps he stares at you and smiles; that could mean he likes you, too.
Can you feel when someone is attracted to you? Yes. When someone feels you are an attractive person, some things come up between you that aren't there otherwise. The clues aren't always obvious, but you can see some of them by paying attention.
Guys typically scan your body if they think you're attractive or they're trying to flirt with you. He might also be checking you out because he's too shy to approach you. Watch for other flirtatious body language signals, like prolonged eye contact or leaning in toward you.
Cross your legs at the knee When you're sitting down, you should cross your legs at the knees, especially if you're wearing a skirt or a dress. If you're flexible enough, then you should cross your legs a second time by wrapping your foot around the back of your ankle.
If a guy is interested, you'll find that his body will lean forward toward yours. This move can be either very subtle or extremely "in your face" (literally). It's his way of letting you know he'd like to get closer. Once his interest is piqued, you'll both find it hard to pull away!
