Well, I have a solution to your PDA-blaming. Just keep the touchy stuff to a minimum in school. Sure the teachers are judgemental, but hugging and kissing in school is a real harm to your image. School isn't the place for that kind of thing... It makes you look like you lack self control. Whether or not that is the case, school just isn't the place for that sort of thing.

Judgemental parents are another issue. I can't exactly advise you on that, since I have a pair of them myself.
