This First Kiss video by Tatia Pilieva is an experiment of having two strangers kiss in front of a camera. Awkward smiles, giggles, and rosy cheeks then soft vulnerable lips connect. A kiss is a romantic gesture, a sense of openness to taking a chance, sharing a sweet side of humanity. Sometimes there is a tongue slipped, or a little bite action, or perhaps a shared breathy exhale.
Research suggests that men transfer testosterone through their saliva, which stimulates a woman’s sex drive. This suggests that the wetter the kiss the better because this helps reproduction and the perpetuation of our species. The rewarding neurotransmitter dopamine spikes with kissing. And the bonding hormone oxytocin rises as well as serotonin rising with a kiss and especially when falling in love. One study found that 66 percent of women and 59 percent of men say that the quality of the first kiss can determine if a friendship can become romantic.
