Don't know what the situation is now-a-days. Hopefully something can be done for you.
I recall when I was at school, back in the 60s, I had similar problems.
My school was all boys. Most were utterly repulsive, especially those around my age. The younger ones were cute and funny, but in no way attractive. A few older ones were nice, but tended to get rather agressive if they thought, for a moment, that they were being admired.
Sorry that it's not particularly helpful, but might be useful to know that the problem is not new.
Needless to say, I just kept my head and eyes down.
