Along with the oxytocin and dopamine that make you feel affection and euphoria, kissing releases serotonin — another feel-good chemical. It also lowers cortisol levels so you feel more relaxed, making for a good time all around.
Good kissers are soft but passionate. They practice good hygiene, know how to move their lips and tongue to make the kiss feel passionate. They listen to their partners. They kiss confidently and make their partners feel wanted.
You Get "Butterflies"
"Your biological stress system is actually activated when you have your first kiss," Seiter says. "But, this doesn't mean you're stressed out. You'll experience increased heart rate, sweating, or butterflies in your stomach; a physiological excitement response."
Sometimes they feel love. If you are in a relationship with the guy you're kissing, he's probably thinking about how much he cares about you. Even if you're not in a relationship, the rush of oxytocin released while your lips are locked is sure to have him feeling warm and fuzzy about you.
Don't make it last too long — about 5 seconds — and be how long first kiss should kiss to pull away soon. Give yourself a bit of time to get ready and only wear clothing that check this out you feel confident.
Whilst bad breath, a darting tongue and a wet sloppy kiss are rated as the biggest kissing turn-offs according to science, it might also be your smell, taste or even your pheromones that's causing the problem. Being a bad kisser can be a deal breaker, but kissing is more complicated than most people think.
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.
Not everyone is comfortable with teeth during a kiss, so it's generally best to stick to a gentle tug on the lips. Anything more than that might be worth a conversation to touch base on what you both feel comfortable with.
You've probably never timed it, but maybe you've wished it lasted longer. In John Gottman's relationship research, he was able to find that six seconds is the length of a kiss that can actually create a connection with your partner. In fact, he recommends you have at least one six-second kiss per day.
Stimulating the nerve endings on your lips
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.
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.
Metabolic boost – kissing burns kilojoules. The more passionate the kiss, the greater the metabolic boost. Healthier mouth – saliva contains substances that fight bacteria, viruses and fungi. Deep kissing increases the flow of saliva, which helps to keep the mouth, teeth and gums healthy.
For starters, the pleasure that you get from making out is literally the result of a hormone, oxytocin, being released when you're kissing. Not only is it a chemical that makes you feel generally happy, but, as psychotherapist Jonathan Alpert told Bustle, "This [also] creates a bond and a feeling of connectedness.
Most people are quite happy remaining dry during a kiss. Your tongue should never be long, wet and limp; this person's face should never have a wet upper lip, wet lower lip, wet cheek or wet chin.
The sexual connotations of the phrase "make out" appear to have developed in the 1930s and '40s from the phrase's other meaning: "to succeed". Originally, it meant "to seduce" or "to have sexual intercourse".
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.
There are over 100 billion complex nerve cells liberally spread throughout the lips. They are the gateway to tiny neurotransmitter molecules that help trigger hormone release including dopamine, oxytocin, serotonin and adrenaline. That first passionate kiss causes dopamine to spike in the brain.
The anticipation of a kiss increases the flow of saliva to your mouth and gives your teeth a plaque-dispersing bath. Bad breath can't be passed on to another person via kissing.
