It’s crucial to get the first kiss out of the way quickly if you want to build instant attraction. Generally, you won’t sleep with a girl the same night you first kiss her—unless that kiss happens right when you meet. If the kiss comes at the end of the first date, the momentum fades and the hookup often gets delayed until later. But when it happens early, the spark ignites right away, creating natural chemistry that can lead to something more that same night.
