Masturbating

so i’m 14 so i’m fairly young but like yeah i masturbate but a lot of my friends that are girls talk about it like it’s gross as hell and i’m just sitting there like “yeah haha that’s gross”. Ik it’s not a bad thing but like i don’t get why they find it so gross??? like ik a lot of girls in my school do but it’s seems the people i talk to don’t but who knows maybe they are lying to cover up that they do.
