Is it normal to kiss in public?
Depends.It depends
Yes, plenty of people kiss in public, though what feels appropriate depends on the setting and the people around you. A quick kiss is widely accepted; longer make-out sessions can feel awkward to bystanders.
A kiss in public is pretty ordinary—couples do it to show affection, say hello, or say goodbye. How comfortable people are with it varies by culture, venue, and personal preference.
A quick kiss usually barely registers. More intense making out may draw looks, especially somewhere quiet, family-oriented, or formal. As long as you and your partner are both comfortable and you’re mindful of the setting, there’s no universal rule against it.
