She is very hot and in her 20s. But those signs, could also be due to the sexual topic we are discussing in the course. Anyways, We hold eye contact from distance very often for a long time, she licks her lips (very often when she looks at me) then strokes her hair and then looks down. Her feet is sometimes pointed towards me and I think she also copied my behavior like when I sit with crossed arms, she does the same (but not sure here, maybe she doesn’t want to be approached.) At some point, she was talking with a student, but looked at me and nodded. So I wanted to check the waters. She was sitting, I went to her said „Mrs.“ waited a good second, but she didn’t turn around, so I just asked her whether I can sign my name into the list. (Thought, after she didn’t turn around that she doesn’t want to be approached, maybe because of the other students or the sexual tension) It was very tricky. She was in a submissive state it was obvious. My question is, do you guys think those signs are enough to ask her out?
