Is it normal to cuddle your cousin?
Depends.It depends
Yes, cuddling your cousin can be normal if it’s affectionate and you’re both comfortable with it. Families vary a lot in how physically close they are.
Some families hug, cuddle on the couch, or lean on each other without thinking twice; in others, that would feel unusual. Cuddling by itself doesn’t have to mean anything romantic.
The main thing is that you both genuinely want it and feel comfortable. If either of you seems unsure or asks for space, respect that—no family relationship makes someone owe you physical affection.
