Where can i find my g-spot?

i cant get any pleasure from myself at all (baring in mine that i am still a virgin) ive tried everything, i even went out and bought a rather expensive vibrator. it does nothing for me i dont know what to do anymore? it does hurt when i use my vibrator, could this be the reason im not feeling any pleasure? i know its a odd question but i would really appreciate it if someone could help me :\
