mistresslggi unsurprisingly the children aren't with me now, so I can't ask them what exactly makes them feel uncomfortable. The point of the thread was asking if it was appropriate for a PE teacher to follow girls who post pictures in barely there bikinis, posing in an overly sexual way (not just body builders-read the OP peeps.) showing lots of boobs & bums. That is the point of the thread.
It's obviously completely inappropriate for him to have that on his public social media. He should be fully aware of that already, but since he is not, the HT should be making it clear - his social media should be completely private because it is not appropriate for young teens to see, or to be made privy to, any element of the sexual life of their teacher - even if they are the ones who sought that information out. A male teacher working with young girls, especially a PE teacher, ought to be aware and conscientious about the boundaries between teachers and students. It's a safeguarding issue if he is not. So you are right to raise it and certainly the HT should be aware that it has happened.
It's right that teachers should be allowed privacy and children should be made aware that it's not okay to invade a teacher's privacy too. But we have to remember these are 13/14 year old girls. We probably all would have snooped on our teachers when we were that age, unless you were completely devoid of curiosity I suppose. Again, if you are teaching that age group, and especially if you're responsible for their physical education, you need to be aware of what the risks are and conscientious about boundaries.
Maybe from his point of view, he just didn't realise his students would look at his SM. If so, he now knows, and if he is a decent, professional teacher, he will take the opportunity to reflect on the set of issues that this touches upon.
Another thing that occurs to me is I would not have liked a male PE teacher at that age, either. It is a time when your body is changing and the idea of being physically vulnerable in front of a young male teacher must be mortifying to some of the girls, as it would have been to me. I'm not surprised some of the girls are saying they feel uncomfortable - I would think that they probably just don't want to be looked at in any way at all. I definitely didn't at that age.
