Is the temptation for a teacher to be romantically involved with a student always there or is it a very small minority that have this issue?

Most teachers would not jeopardize their job, reputation, and probably not attracted to students but I don't know if the temptation is there whether they admit it or not. Like I'm not sure if teachers feel any sort of way about particular students but try to avoid it and not show it.

I ask because I became a HS football coach for the first time and it was the first time going back to HS since I was that age. I felt very weirded out when i still found certain students attractive or crushes like I did when I was a student. I was like wait, I'm an adult why I am feeling this way? Is something wrong with me? I hide it and do my job but there's an uneasy feeling of trying to be professional when I know how feel deep down inside.

Then its even more awkward when certain students show attraction or give me signs. I'm so confused because I haven't been in this situation before as an adult. I'm just like damn am I that person that gets involved with students and you hear about them on the news? Maybe now I see why it happens but its a weird feeling of trying to hide it and be the teacher. I just wasn't expecting this when I got the job. Can anyone relate or do I just need help?
