First time with a man and I feel disappointed

I am 20 and fit. So the other day I had my first time with a man. I considered myself to be a bottom and always have. He showed up to my car and wiped out, his BBC, and I loved it, but when he finally put it in me, I felt disappointed because it didn’t feel like much. I don’t know if it was the way he was fucking me or if I just overall had a bad experience. I let him finish inside of me, but I crave more. He didn’t really fuck me hard, so I don’t know if that would feel better or if someone with a bigger cock would. Any suggestions would help greatly.
