Is it normal to kiss your siblings?
Depends.It depends
Yes, plenty of families kiss siblings as a sign of affection, though what feels normal varies from family to family. Cheek or forehead kisses are common; kisses on the lips are more personal and depend on everyone’s comfort and boundaries.
Families show affection in different ways. Hugs and cheek or forehead kisses between siblings are common, whether you’re kids or adults, though some families are less physically affectionate.
Kissing on the lips is less common and can feel uncomfortable to some people, but it isn’t automatically sexual. What matters is that everyone involved genuinely wants it and can say no without pressure. It’s fine to set a boundary—or to be affectionate in a way that feels comfortable to you.
