problem with my 🐱???

i'm 17 going on 18 & never been in a relationship. virgin. i masturbate though. w the jet stream of the shower head or just my fingers on my clit. but i don't think i've ever reached orgasm; my clit feels this tired sensitive feeling after only a couple minutes to the point i can't touch it w/o feeling uncomfortable.😰  idk how to explain it. putting my fingers in my vag just feels uncomfortable and sometimes painful. 😥😥 is there something wrong w me? will i get this worn out this quick when i do get 2 have sx? why does this happen? anyone rel8? advice? 😖😩😓😒
