You don’t want your first kiss to take place in a noisy, messy setting, and you probably don’t want it to be somewhere too brightly lit or conspicuous, either. Consider whether you will be locking lips in front of an audience and ask yourself, ‘Is it appropriate to kiss here?’
A crowded bar or dance floor is fine, but if you’re in a low-key environment or surrounded by small children, it might not be the best place to suck on each other’s faces. Consider others around you and their reasonable aversion to PDA, plus the comfort level of your date. A low-lit, quiet and romantic setting is your best bet here.
