how to finger myself?🤔 help

hi girls! i feel like i can’t masturbate myself. i mean, it doesn’t feel good when i am fingering myself. i can’t have an orgasm and even enjoying this moment. do you have any tips on how to properly finger myself because i’m a little bit scared that when i am going to have sex, i won’t enjoy myself i have to fake it😫

also, i can’t buy any vibrators or sex toys.

thanks!
