My vulva was itchy and I can't feel my cilt

When I was 15 years old, I had sex for the first with my boyfriend. I was young and uneducated about sex. we belived you take a girls virginity without a condom.Biggest mistake ever. A couple of weeks later, my vargina was very itchy at night and when i had to urinate there was a strong unpleasent odor. Also, i had to go to urinate every 3 mins and barely came out. I feared I had a STD & i didnt want to find out. The symptoms ended up leaving. since my first time, I never had sex again because i feared i'll spread a std . 4 years later, I never ever been sexually excited, ever ! not with porn, girls, toys, by myself, nothing. I can't produce lubercation for myslef & I seen a GYN & she sed my vargina was very dry. I am not sure if a untreated std for such a long time can cause damage to the clitourous. But I cant feel my clitourous, not for pleasure or nothing. My period is normal but I bet my life there is something wrong. I know im not suppose to dig in my vagina but i did & white mucus came out. I also feel uncomfatable when I urinate or random days. I took an std for claymidad & gonherea & it came back neg. I want to be intimate again but I am sure there is something wrong. please help.
