When I was 12, I had my first kiss outside of a mall at a friend’s birthday party. She was turning 12 and I thought it was the coolest thing when a friend of hers started liking me, asked me to be his girlfriend, and grabbed my hand and kissed me outside the mall at 7:00 when it was dark in our small Michigan town. When he touched his lips to mine, I thought it was amazing! But then, I started to wonder why it felt so good to have his lips pressed up against mine! So why does it feel so great to snuggle up with your honey on a couch and neck in the evening? Well, it’s all about the chemistry of kissing.
There are many reasons why kissing feels so good, but according to MedBroadcast, the lining on the outside of the lip is continuous with the lining of this inside of the lip. These membranes have many nerves inside of this lining and very sensitive, causing pressure to the lip coupled with strong emotions to make the kiss feel great! Kisses also feel good because there is a release of endorphins within a kissing.

Endorphins make many acts feel good and kisses are in now way left out. Kisses feel wonderful as the buckets of endorphins are dumped into the bloodstream. The kissing also feels good because according to CNN, five of the 12 cranial nerves are involved in contact with the lips. There are impulses that bounce between the lips and the brain rapidly which involves several chemicals. The most prevalent chemical present in a very passionate kissing, causing it to feel wonderful is a release of dopamine in relatively high amounts. This causes a feeling of euphoria we may not otherwise receive and causes the kiss to feel amazing. So on the first date with the guy who you really liked from AP Biology, a kiss finally happens while you’re thinking about gene therapy, even more dopamine is released than when you’re thinking about electrophoresis!
In addition, because there are chemicals being released, blood vessels will dilate during a kiss and the pulse quickens. Pupils dilate in the process as well which causes a physical reaction to something chemical, which is the closing of your eyes due the fact that pupils usually dilate in the dark. Of course, all of the wonderful an interesting chemical changes that occur within a kiss will be only found in kisses at feel good and they give us information that our bodies think we need about a person that we are considering dating.
Kisses can be wonderful! You feel the warmth of another body pressed against yours, hands are tangled in hair, cheeks and fingers are warm. But now you know the chemistry behind the kiss that feels great!
