Orgasms

im 16 and ive tried multiple times to masturbate but i dont feel shit😐 so i just gave up and dont do it lol. when i was with my ex id fake orgasms. i mean i would be wet but id never cum.. well feel that "amazing" feeling that everyone talks about. and my current boyfriend tries to rub my vagina and i feel nothing. until he fingers me then i feel a little sensation but i know its far from orgasms..? i looked up online what this is. and it says that my body doesnt know how to have an orgasm or that i dont feel the sensation..😕 but if i tighten my vagina or cross my legs i can get an orgasm (im so weird) can anyone do that?? or is it just me?
