Why it’s hot: “The novelty of a first kiss drives up dopamine in the brain, and kissing a long-term partner releases oxytocin,” both of which are feel-good, put-you-in-the-mood brain chemicals, says Helen Fisher, PhD, a love and sex researcher at Rutgers University and chief scientific advisor for Match.com.
How to activate it: Even if you prefer sloppy kisses (Fisher says men like them because saliva has traces of testosterone in it), she warns that most ladies aren’t so into it. Keep your lips firm-but-soft, and let the lady take the lead. She’ll probably kiss you the way she wants to be kissed back, which will definitely turn her on.
