First, you also want to have something to do with your female teacher.
Second, but you don't like your female teacher very much. It's just a psychology that all men have. You're afraid of what responsibility you'll take after you fuck her. You certainly don't want to marry this female teacher.
Third, your female teacher comes to your door to prove that she has no boyfriend and can't be a virgin, which is a bit coquettish. She would never say that you fucked her several times and then forced you to get married.
Fourth, aren't you in college now? When you go home after graduation, she won't follow you home. What are you afraid of?
My opinion is, be bold, or you will regret it later ... if you don't have a girlfriend (of course, even if you do, your conscience is fine)
In order to complete the task, I will answer your questions in a boring way. If you think I'm right, adopt.
