this is really embarrassing but i need help

(warning i’m rlly awkward and don’t really know how to explain myself or what i’m talking about) i’m a virgin and the first time i’ve ever done anything with anyone happened a few days ago. we both started having sex and when i actually like put it inside i was already really nervous. i started thrusting and my dick was really sensitive when i was going in and out. i honestly think its just like a one pump chump thing or maybe i’m just super sensitive to it seeing it was my first time, but it felt like it was TOO un natural yk? like i swear i don’t think i went in and out more than 5 times before i was like “okay i need a second” on top of that it was without a condom so it made it even worse. does anyone know if it was just something that happens or is that genuinely a problem
