ORGASM

Okay. So I have never cum before. But last night during sex, i felt like his dick hitting against this harder part idk...it felt like pressured and kinda felt weird... was that my g spot? Also, when he was touching me and fucking me at the same time, i felt really nervous and overwhelmed and like i had to pee or something... was that me starting to have an orgasm? I stopped him anytime it happened bc it was too overwhelming.
