Dopamine is released when you do something that feels good, like kissing and spending time with someone you're attracted to. This and other “happy hormones” make you feel giddy and euphoric. The more you get of these hormones, the more your body wants them.
They are packed with sensitive nerve endings so even the slightest brush sends a cascade of information to our brains, which can feel very good. Kissing activates a very large part of the brain associated with sensory information because we're at work making sense of the experience in order to decide what to do next.
Making out increases intimacy and bonding
As you lock lips with a partner, your body acknowledges this as a way to form an attachment. When you begin feeling attached, you start to crave closeness with a partner for a sense of connection and security.
Making out can be an enjoyable activity all on its own, without it progressing to anything further. If you and your partner don't want to move on to more intimate activities, simply make out until you both feel satisfied. However, making out can also be a powerful part of foreplay.
A feeling of relaxation and well-being follows." So apart from feeling good physically, making out (especially with a new partner) can make you feel good mentally, too. And besides, it can be exciting to move into uncharted territory — aka new levels of intimacy — with someone new.
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.
Make eye contact.
Meet your kissing partner's eyes and give them a little smile to show that you're ready for some action. You can also gently lean your forehead against your kissing partner's, put your hand on their face, touch their leg, or even give them a quick peck on the lips before you start kissing.
Kissing, licking and sucking are all recommended and even some gentle biting can be acceptable as long as you take it easy. No matter where your mouth ends up, it's probably going to make her feel good.
You can feel his heart race.
You'll probably also notice that he's blushing or breathing a little more heavily. A passionate makeout session releases adrenaline–not only does it kick up his heart rate, but it also boosts his energy.
Kissing has also been connected to greater sexual satisfaction. Locking lips—particularly with saliva exchange—serves as a way to facilitate arousal, which was found to enhance a sexual experience for most people (3).
Guys & Girls Can Both Feel Emotionally Attached After Sex
“Men and women have reported similar experiences when it comes to feelings of attachment after intimacy,” he says. “The difference is how those feelings are expressed. In my experience, men become much less emotionally uninhibited, at least for a short time.
At its most basic, kissing is a mating behavior, encoded in our genes. We share the vast majority of those genes with the mammalian species, but only humans (and occasionally our close primate relatives like chimps and bonobos) kiss.
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.
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.
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.
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 want to see where the kiss takes you.
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.
If you're really into this dude, the kiss sends shock waves throughout your body that can increase blood flow to certain areas. Think stiffened nipples, fluttery stomach, tingling genitals. Sensing the hubbub, the adrenal glands unleash adrenaline.
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.
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.
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.
A kiss transmits smells, tastes, sound and tactile signals that all affect how the individuals perceive each other and, ultimately, whether they will want to kiss again.
