Ask her opinion

Out of curiosity, you decide to ask your teacher a question. "Miss Anderson," you ask, "are you alright with having a dick now?" The woman sighed. "Well, there's nothing I can do about it, can I?" Your teacher responded very manner-of-factly, but you can also feel that she is annoyed.

"Do you want me to give you your vagina back?" You're not actually planning to do that, but you're very curious what is going through your teacher's mind right now. Miss Anderson responded in a somewhat conflicted way: "I... I would love that, but you're allowed to do anything, so don't let me tell you what to do." She is biting her lip.

You decide to help her... in a way. "I wish miss Anderson has her vagina on her forehead," you say, loud enough for your teacher to hear. Miss Anderson's forehead deformed and a few seconds later, she showed a clear slit right between her eyebrows. "Is this better," you ask her.

"I, uhm... sure," miss Anderson responds in a very conflicted manner. It's clear that she doesn't actually appreciate the change.
