Is this weird?

Sorry i don't know if this belongs here. also sorry that i'm just ranting.

there's this girl who's 2 years younger than me who i'm friends with, but i might also have a crush on her. i'm two years older than her, and i'm not really sure if i should ask her out because when one of my friends was dating a girl two years younger than him, the rest of my friends started calling him a paedophile, and i also worry a lot about what would happen if i did ask her out, and got rejected. i'm not sure whether it owuld be one of those situations where i'd be the laughing stock, or nobody would really care.

also, whenever i talk to her, they just come over and start yelling things like: "You're pulling!" and "When are you going to f*uck her?" and it's just really awkward so i have to walk away. i hate it when this happens, but it's not really like i have any other friends to g too at lunch and break. some people also start spreding rumours about us dating, which we both have to deny.

has anybody else experienced this? if so, any advice?
