I had sex with my teacher
I'm on the swim team at my school, and once after practice my coach pulled me aside. He wanted to talk to me about my grades, since I couldn't stay on the team if I get an F in any of my classes. I'm not doing well in chemistry, so he was telling me that I should focus on that a bit more. So I'd stay after school for chemistry several days to get my grades up. My chemistry teacher was nice, and I would often end up bumping into him outside of school.
Usually at the park or library, but we chat and go our separate ways. He suggested we go out sometime, and I said yes. At the time I was thinking of him as a guy instead of my teacher, since he's 21 and I'm a senior. I didn't think the age difference was a big deal. Now I realize that was a bad decision. We went out to see a movie, and had a few more dates after that. One weekend he invited me to his house. Simple things led to more extreme things, and we ended up having sex.
I know he could lose his job if anyone found out about this. I don't know what to do, I do have feelings for him, bu the fact that he's my teacher makes things complicated for us.
