First off, I wanted to thank everyone for their responses. It was really surprising to open my mailbox this morning and see how many reactions my post conjured. Thanks a lot for all your input.
I think the 70's are comparable to the view on things like sex and relationships of today. I always hear crazy stories about those times, so for you to have been like me, well it does make me feel better.
I guess it's stupid to feel pressured, but I've never been able to deal well with peer pressure. In Highschool my reaction would be to follow the herd, these days I mostly don't care, but because relationships and sex are such alien things to me, I have no reference point. It's nice to know there are others like me out there.
To answer your question: I was mostly alone in this. I remember a teacher trying to interfere, but he ended up making it worse. The students realized I told on them and as a thank you gift they demolished my then new bike. I decided after that I wouldn't call in for help again. My parents urged me to take karate lessons, if only to help gain confidence. It helped a little, but because I learned to hit I started doing it too. It pretty much meant that the wallflower now had a bite, which didn't really improve my popularity. My classmates then decided to approach me in groups, so that was the end of that.
I do realize today that if my time at school wasn't so shitty, I may have gotten to university afterwards. In my country, you have levels within Highschool and I sank a few levels in an attempt to avoid classmates. That didn't help; their grades weren't great either. I'm making up for it today, but it has cost me 3 extra years of education in college. Funny how things work out.
My, my post has gotten way too long. In any case, I want to thank you for your kind words and advice. It really helps.
