masturbation is so confusing

masturbation is so confusing - i am a 16 years old girl whos only seemed to get 'mini orgasms' from massaging my labia and ive started that quite early in my life. i try to rub my clit but when i find it, it seems so incredibly small and i have to be careful before i lose it again. i can't even feel much pleasure rubbing my clit, just tiny sensations. same thing applies with fingering myself. I've been completely aroused enough for insertion of fingers but i cant seem to feel anything down there - its almost as if its numb?? even if i go slowly and in and out, perhaps even try to look for my g spot and stimulate whatever the hell is of my clit, i dont feel anything. ive really tried everything, stimulating clit (tiny ass one), inserting fingers when fully (HELLA) aroused and both at same time. the only thing i feel that is remotely pleasurable comes with playing with my nipples and the massage of my labia that gives mini orgasms. im trying to get the big O and I'm scared of when i become intimate with my bf, i wont be able to orgasm with inserting fingers or stimulating clit and the absolute lack of feeling is incredibly frustrating and makes me feel like im just insensitive down there. can someone help? has anyone faced this before? how did they revive or get some sort of pleasure from masturbation? thank you all so much
