Second date sex?

Lexie

So... I really like this guy, and only went on one date before. We watched movies at my house and cuddled, and it was great. This second date was at his house, and we started watching stuff, then we were making out... we were really getting into it, and he ended up eating me out twice, and then we had sex. He made me feel really safe, and asked me if I was okay with it every step of the way, and it was honestly amazing sex, yet I kinda have this pit in my stomach. That was my first time, and I didn’t even think that it was something I would do on the second date... idk I feel kinda gross about it, and then I feel bad for feeling gross... my emotions are so confusing, does anyone have advice?
