I got extra credit and I am proud of myself.
You mean in school? What did you do?
I'm talking about my teacher, he gave me extra credit for performing oral sex on him.
That's unfair to the other students who actually did the work. Your behavior isn't criminal but neither is it laudatory. Your teacher, however, should be reprimanded.
I think he was doing it to reduce his stress levels towards a certain student.
It doesn't matter if he was stressed, doing such acts with a student is immoral and I believe you shouldn't keep doing such things. Wouldn't you be more proud to get extra credit based on your own merit instead of sleeping with teachers?
