Are my friends doing the right or wrong thing?

My friends know I love dolls like moxie girls or barbies and sometimes my friends will buy me them and give me them at school they know I'm embarrassed by lilting them because I'm 13 and they will tell me in crowded places here's your doll then hold it high I go all red it's embarrassing I don't like it I have told them nott to but they still do what can I do to stop it they also will say how cute it is and if a boy ever talks to me they always have to say do u like dolls because caityboo douse I don't like it but not many people like me at school I am not hated but people think I'm a baby
