Lips may have evolved first for food and later applied themselves to speech, but in kissing they satisfy different kinds of hungers. In the body, a kiss triggers a cascade of neural messages and chemicals that transmit tactile sensations, sexual excitement, feelings of closeness, motivation and even euphoria.
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.
If pheromones do play a role in human courtship and procreation, then kissing would be an extremely effective way to pass them from one person to another. The behavior may have evolved because it helps humans find a suitable mate—making love, or at least attraction, quite literally blind.
French kisses can be more stimulating than kisses without the tongue since the lips, tongue, and other parts of the mouth are powerful erogenous zones that contribute to sexual arousal.
If you want to just kiss without tongue too, it's totally fine.
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.
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.
Anthropologist, Helen Fisher says that when we partake in mouth-to-mouth kissing, we share saliva which has testosterone in it which enhances our sex-drive. Kissing also stimulates the brain hormones, dopamine and oxytocin– both of which promote bonding and attachment in human beings.
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.
It turns out, it may not be that elusive after all. It may just actually be... chemistry. Saliva is like a chemical cocktail, and hooking up may have evolved to help us quickly tell if someone is a good mate or not, Fisher said.
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.
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.
Most often, guys breathe heavily when making out due to feeling aroused or extremely excited about being with you. Keep it in mind.
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.
When you kiss someone, your body releases happy hormones. 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.
But they often work together to create different levels of relationships. Also, these functions vary among people. So while one man may get emotionally attached after kissing, another may not. It is highly subjective, depending on the man, the woman, and the kind of chemistry they have.
In actuality, kissing with eyes open doesn't indicate anything negative about the guy or his feelings towards your relationship. Some guys just enjoy the visual input that comes from kissing with their eyes open. These are some of the many reasons why guys kiss with their eyes open.
A simple kiss evokes emotions of love, care and admiration. This is said to be the most intimate act of love that gives you an overwhelming feeling, like butterflies in your stomach!
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.
When one person's lips touch another person's, the hormone oxytocin is released. Oxytocin gives us a feeling of being bonded to the person we are kissing. A sense of trust is associated with a rise in oxytocin while a feeling of relaxation corresponds with a simultaneous decrease in cortisol.
Kiss someone when you feel ready, regardless of how old you are. Around ages 12-15, people often start having their first kiss. Don't feel pressured by other people your age kissing people, and don't rush into kissing someone if you are apprehensive.
