Kissing comes naturally but our techniques can evolve. We're kissed from birth and other social animals seem to kiss, too. Bonobos — a type of Chimpanzee — have been known to smooch for up to 12 minutes straight, while giraffes like to entwine necks, and even fish touch lips, Kirshenbaum said.
A kiss might seem like a natural thing to do for most of us, but the scientific jury is still out on whether it is a learned or instinctual behaviour. Approximately 90 per cent of cultures kiss, making a strong case for the act being a basic human instinct.
The thought of touching someone's tongue with your own tongue — and doing it with minimal drool — can sound weird or tricky. What if you thrust it in too hard? What do you do with it once it's in there? Don't sweat it because with a bit of practice, French kissing will come naturally.
Others argue that the origin of kissing is biological—much like how we see birds and other select wildlife choosing mouth-to-mouth feeding techniques, it could also be seen as a mating ritual with a survival purpose. Bryant has counter-argued that kissing wasn't a generally-known practice at the time.
As health and wellness expert Samantha Morrison explained to Bustle, "Kissing is engrained into human nature." For starters, the pleasure that you get from making out is literally the result of a hormone, oxytocin, being released when you're kissing.
A long kiss releases dopamine, oxytocin, and serotonin, feel-good chemicals that will make him smile. A single smile produces endorphins, another hormone that lifts his mood. Endorphins also create a “feedback loop” that will make him smile over and over.
A butterfly kiss is an affectionate gesture made by fluttering the eyelashes against someone's skin or eyelashes.
You don't have to use your tongue through the entire make out session. If you want to just kiss without tongue too, it's totally fine. When you ARE using tongue, your go-to move when Frenching can be a massage between your two tongues. You can also try different things and see what feels most comfortable.
According to Medical Daily, DNA remains in the lips for at least one hour after kissing another person, regardless of how long the kiss lasts.
It takes chemistry
That fluttery feeling you get when you're kissing a new partner – the racing heart and spiking blood pressure – comes from dopamine. It revs your engine, but you can thank the love hormone, oxytocin, for bringing you back for more years after the novelty has worn away, Kirshenbaum said.
Most people can't focus on anything as close as a face at kissing distance so closing your eyes saves them from looking at a distracting blur or the strain of trying to focus. Kissing can also make us feel vulnerable or self-conscious and closing your eyes is a way of making yourself more relaxed.
Adrenaline Is Unleashed
"The heart rate goes up, muscle tension increases, our breathing rate speeds up, and blood flows to our internal organs." It's why you might feel "weak in the knees." But this feeling also plays a role in assessing your chemistry.
Not every first kiss, though, is a great kiss. They can be awkward, especially if the moment is not right or even forced. Even still, we are physically wired to tell the difference between a bad kiss from a good kisser and a "this does nothing for me" lipsmack.
When kissing, romantic partners not only exchange bacteria and mucus, they also pass on some of their genetic code, it has been revealed.
LIZZY KISS
This is a similar type of kiss wherein both the partners stick out their tongues and kiss each other without the use of their lips.
Unlike other octopus species, Larger Pacific Striped Octopuses mate in an intimate clinch with their beaks and suckers pressed against each other.
The Spiderman kiss was an iconic moment in the popular film franchise. It involves hanging upside down while kissing, but can also be done while lying flat. With a little maneuvering, you can pull off the spiderman kiss with a friend or romantic partner. Take precautions, however.
A kiss on the neck usually means that he just can't get enough of you. If he kisses you on your neck, it means that he loves you and is passionately drawn towards you.
He smiles during or after.
Smiling while smooching might be an indication he's not only happy to be kissing you right now, but that he's been wanting to kiss you for some time, and is overcome with elation and a sense of victory.
Most often, guys breathe heavily when making out due to feeling aroused or extremely excited about being with you. Keep it in mind.
People can make out anywhere from a few seconds to an hour or more. Making out can also lead to unprotected sex whereas brief kissing may be safer and doesn't tend to lead to sex.
A passionate kiss can spike the neurotransmitter dopamine, which is linked to feelings of craving and desire. Oxytocin, known as the “love hormone,” fosters a sense of closeness and attachment. Adrenaline boosts our heart rate and can make us start sweating as our bodies begin to anticipate what might occur later.
A study suggests that the dopamine produced by kissing can stimulate the same area of the brain that is activated by the use of cocaine or heroin. This is one of the reasons why kissing is so addictive, and you may get hooked to it.
