numb in vagina

hi there, im 18 and after much thought and consideration i have decided to ask for help and advice.

when i was 14, i fell for a fellow classmate, it soon turned into a serious relationship and we started enagaging in sexual activity soon after. from the first time he perform oral sex on me, i felt nothing inside my vagina and from the first time we had sex at 16, i also felt nothing. neither pain or pleasure. As my boyfriend and i were both virgin, we didnt no abnormal from normal, and i never worked up enough courage to tell him, so i pretended that it always felt great. no doubt, i knew something was wrong with me but i feared telling my friends or even my parents.

Now at 18 i met a beautiful guy, and were both crazy about each other. i love him, but i cant bring myself to tell him that something is wrong with me. it would change alot if i did, beacuse we have sex so frequently and i also pretend that its good even though i cant feel it. i know the appearance of my vagina looks no diffent from other females, as im sure he would have pointed it out.

im not sure what to do. i cant tell my parents, beacuse they will hit the roof and might end up disowning me as a daughter if they knew i was having sex.

i have no idea whats wrong with me, i feel nothing in my vagina, well sometimes on rare occasions i feel pain if my b/f thrusts too deep but other than that, i feel nothing. i still have my monthly periods and everything, i just cant feel pleasure unless i have clitorus stimulation. i crave so badly to make love to my boyfriend and be able to enjoy it. my greatest fear is not being able to have kids.

i know i need to see a doctor, i just need to work up the courage.
