Is it normal to like being tickled?
Depends.It depends
Yes, it’s normal to enjoy being tickled, though plenty of people find it uncomfortable instead. What matters is that it feels fun for you and everyone involved respects your limits.
People react to tickling differently: for some it’s playful and fun, while for others it’s irritating or overwhelming. Liking it doesn’t mean anything unusual about you; it’s just one of those personal sensory preferences.
As with any physical play, make sure the other person knows what you enjoy and stops when you ask. Tickling is only fun if you’re actually having fun.
