Tongue Kiss
Tongue Kiss

A single kiss is capable of triggering a whole series of sensations thanks to the nerve endings that at the moment explode and are transmitted to the brain. In just a second, neurotransmitters such as dopamine, serotonin, epinephrine and oxytocin are released.

But when a couple uses the tongue to kiss, the exchange of saliva generates that the man sends testosterone that in the woman works like sexual aphrodisiac. They feel more attracted to someone with a different genetic code because in this way offspring are secured, according to Sheril Kirshenbaum, a scientist at the University of Texas.

“When all the information reaches the brain, it assesses whether it likes it or not, rejects it or accepts it, and when a person is kissed, chemical reactions are different than when the subject is unknown,” says David Bueno i Torrens, biologist.

However, the actions following that kiss will depend on the dominant neurotransmitters. For example, when dopamine is increased more, the woman feels stable, but when there is more serotonin is excited. But not everything is honey on flakes, because this changes after falling in love, when the adrenaline decreases but both are more comfortable in the relationship.
