The question is fact and circumstance intensive.
First, if we are talking about actual pedophilia, ie relations with prepubescent boys, there is nothing "hot" about it or anything remotely acceptable. That will fuck a child up, although I do think it damages girls more than boys.
But I do not think that is what OP means by "pedo." I think he means teenage minors. First, age of consent laws in the United States are high. The only place higher than 16 is Ireland, 17. Much of Europe is 14-15. UK is 16. IIRC correctly, 11 states had an age of consent of 18, but that number has gone up, it seems. Age of consent that high makes this country similar to places like Iran.
Presuming OP is not talking about actual pedophilia but hot teachers fucking 16-17 sophmores or juniors in high school, it is important to stress that men and women are different, and the mechanism of attraction is different for men than women. Women rely a lot more on social proof, such that a young man who had relations to an attractive teacher (in a situation that could get her in lots trouble, losing her job at a minimum) is going to make him very attractive to women, probably for the rest of his life.
For me it also depends greatly on whether she was married or not. No one seems to talk about that (at all), but that's the really only problem I have with a twenty or thirty something year old woman fucking a high school kid.
Here is one absurd example--Baylee Turner was 23 when she had relations with a student who was about 17. Nothing inappropriate about that age difference. They married to prevent him from testifying and now have a child.
I do not have all the answer but I think an age of consent of 16 is absolute folly, especially in a society that is hyper pornographic and sexualized, and excuses and condones all sorts of profligacy and vice in seemingly every other context. If I made the rules I would probably relegate freshman back to junior high, and make age of conset at entry in high school.
Teachers who have relations with student or former students should be fired and lose their license, absent circumstances such as the student was a senior, and a former student so there is no conflict of interest. Criminal charges should only apply when there is a showing of some sort of coercion, quid pro quo etc.
