Is it ok to play with toys?

I'm 17 and recently I've been interested in playing with toys again. I went to Walmart today with some friends and found this really cool jurassic world toy and bought it, when my friends saw me with it, they started calling me "kiddy" or "you're an adult bro" and honestly, it really hurts my feelings and I'm planning on returning the toy, but I just want to ask, is it ok to play with toys? Am I too old to?? My friends do know I have autism, and seem to make fun of me for it but I think they're only joking. Any insights?

Edit: Thank you to all the people that have pointed me in the right direction, you all are valid. I'm going to keep my dino. :)
