year old man to have sex with a 12 year old girl?"
You phrased it at times as "should be able", which is a different question.
The closest you got to asking if it was "ok" or "appropriate" was in regards to teachers and students, and I said it was likely never appropriate (and this was a question with no ages included hence the "likely").
