The dopamine released during a kiss can stimulate the same area of the brain activated by heroin and cocaine. As a result, we experience feelings of euphoria and addictive behaviour. Oxytocin, otherwise known as the 'love hormone', fosters feelings of affection and attachment.
You experience an adrenaline rush: When you kiss someone for the first time, your body will release a burst of adrenaline (the fight-or-flight chemical) which increases your heart rate, boosts your energy levels and gets the blood flowing.
The lips and tongue contain a huge number of nerve endings, which trigger signals to the receptors in the brain. This is what causes the lip sensitivity you experience when having a smooch.
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.
Keep your mouth soft and relaxed.
Both a cranked-open jaw and a closed-mouth, hard pucker aren't the most pleasant to smooch. Keep your lips just-apart enough, allowing the kisses to be soft and deep, and keep your mouth relaxed.
You get all giddy.
A rush of dopamine, oxytocin, and serotonin hits your system the moment your lips lock. With this positive cocktail and a heart-fluttering kiss, you'll feel like you're on cloud nine! Lips are one of your body's most sensually sensitive areas.
Deep kissing increases the flow of saliva, which helps to keep the mouth, teeth and gums healthy. Increased immunity – exposure to germs that inhabit your partner's mouth strengthens your immune system.
Some guys may feel emotionally attached after kissing because it creates a sense of intimacy and connection. Others may not feel emotionally attached because they view kissing as a casual activity.
He cannot stop smiling
You notice that after your French kiss make-out session, he can't stop smiling. If he acts in this way, then it's clear that he enjoyed that kiss. You made his day with your kiss, and he finds you even more attractive. The guy is smiling because he knows that you are a keeper.
When you kiss someone, your lips touch and press against their lips. This can cause your lips to swell up as a reaction to the pressure, and an increase in blood flow within the lips.
According to Ryan Neinstein, M.D., a plastic surgeon in New York City, our lips are made up of blood vessels, which become dilated during kissing.
Basically what this means is that in order for us to fully enjoy that passionate kiss, we automatically close our eyes so our brain can concentrate. 'If we are focusing strongly on a visual task, this will reduce our awareness of stimuli in other senses,' Dr Polly Dalton told The Sunday Times.
During a kiss, this lip sensitivity causes our brain to create a chemical cocktail that can give us a natural high. This cocktail is made up of three chemicals, all designed to make us feel good and crave more: dopamine, oxytocin, and serotonin.
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.
It releases the love hormone
This makes us feel more aroused and can also help to generate a closer bond and trust with our kissing partner. Kissing sends our oxytocin levels through the roof, so it helps to bring people closer together in more ways than one.
when you kiss your partner passionately, not only do you exchange bacteria and mucus, you also impart some of your genetic code. No matter how fleeting the encounter, the DNA will hang around in their mouth for at least an hour.
Examples of physical intimacy include being inside someone's personal space, holding hands, hugging, kissing, caressing and sexual activity. Physical intimacy can often convey the real meaning or intention of an interaction in a way that accompanying speech cannot do.
Ease back out of the kiss, keeping yourself close to your partner's face. After the kiss, pull your head back slowly to give each of you some space. If you wrapped a hand around each other, you can lightly ease off, or hold each other close for a more intimate moment. Look your partner in the eyes and smile.
Today, an average kiss lasts more than 12 seconds. In the 1980s, couples came up for air sooner than that: back then an average kiss lasted a mere 5.5 seconds. 3. Public kissing isn't always allowed everywhere.
They really like kissing you.
If you and your partner are making out and they suddenly reach their hands up to cup your face, they're probably having a good time. You can take it as a compliment and return the favor. They also might stroke your cheek or grab the back of your head. These are all good signs!
Touch their face.
This can add some intimacy to the kiss. You can grab their face with both of your hands and gently pull it closer to your face, for example. You can also try gently caressing their cheek, neck, or even their earlobe. Ears are sensitive areas, so lightly stroking their ear may be a turn-on for them!
