How old were you when you gave your first bj and how old were you?

So I was 14 years old, I was just started my Freshman year and it was with my boyfriend who was 16 at the time. We were making out one night in the dark and we had made out before so I had gotten pretty comfortable with it ( he was also my first kiss). When we were making out I was on top of him and he started to try and push my body down. I knew what he wanted and I wasn’t really comfortable with he. I resisted from him pushing while we were still making out but he kept on trying. Finally after a while I gave up and went down. I was so nervous and felt pretty embarrassed. I pulled down his pants and started to do you know what. I honestly had no idea what I was doing but it seemed like he liked it. I honestly wasn’t happy at all. I started to cry but I wanted to hide it from him because I didn’t want him mad or worried. He then kept pushing my head farther which let to me chocking but I didn’t stop him. After idk how long he finished and said I did a pretty good job. The rest of the night I just laid in bed and cried because I just didn’t know how to feel about it. What really confused me is before all this happened, even my first kiss, I was obsessed with the idea of sexual stuff. Like I just couldn’t wait for it but in the moment I hated it. I still don’t know how to feel about this experience and regret it a bit :(
