Is it normal to kiss your brother?
Depends.It depends
Yes, a quick affectionate kiss between siblings can be normal, depending on your family and culture. If it feels romantic, sexual, pressured, or uncomfortable, it’s worth setting a clear boundary.
Families show affection in different ways: a kiss on the cheek or forehead can be as ordinary as a hug in some households, while others don’t kiss siblings at all. There’s no single family rule everyone follows.
What matters is that you both feel comfortable and that it’s affectionate rather than romantic or sexual. If either of you doesn’t want it, a simple “I’d rather hug” is enough—being siblings doesn’t mean you owe anyone physical affection.
