menstrual cup

i bought a menstrual cup like a while back and had a really hard time using it. i really wanna try to use it again. its an anthena cup i got it off amazon. its squishy and stuff but i think my vagina is too small(??) lol i cant stick it up in there at all, like it'll just fall out lol. i think it wont work since im a virgin maybe?? i dont know if thats a thing though. i would like to know if theres other brands that work better & some tips to get in it there, i think it would be a life saver for me i really want to make it work.
