Is it wrong or unusual for me to want to make a promise to not have "Sex" until am out of high school ?

WOW!
that's amazing that you want to wait and not get stuck into peer pressure and do it just because a guy says to do it and I'm the same way with you on everything! except with a girl lol but yea I'm just waiting till marriage but everything else you said if what I want like everything from "I know the idea of it is something natural" to "so I will be ready and know it is the right time." and "if they...my wishes."
and about just having guy friends. not ALL want something extra but some do. for me I just wanna be friends with girls right now. and see what comes along

Wow. There is just so much you do not know or understand. First of all, sex or celibacy is your choice. There are advantages, nice ones, to being sexually active. There are also at least as many disadvantages too it. Just remember it is your body and your choice and you should make the decision yourself. That brings me too the second issue. From what you wrote, you have been heavily conditioned. You have been fed a line of propaganda with a motive of making you not want to be sexually active. Many of the things you said are so familiar as components of the old line parents feed their daughters in order to try and keep them celibate. Have you noticed that boys your age rarely have these same feelings. You see it all started because parents did not want their daughters producing unwanted mouths to feed. This mental conditioning continues today and most of the conditioners do not fully realize why they do it, it is just what they heard when they were growing up. Try to learn to think for yourself and make your decisions based on a process of logic.
The next issue, true feelings for you. That is again something you have been told to think. It will be much better for you if you can separate sexual activities and feelings. In all probability you will in your lifetime have several sexual partners. If you merge sex and emotion, then each time you change partners you will be emotionally hurt. It is much better if you can be sexual for pleasure and express emotion another way. That is the reason guys do not get hurt by break up as badly as girls. They think of sex as something they do too feel good, and you know very well how girls think of sex. One last issue I would like to mention too you. Making a pledge? Being labeled that virgin. Those are ridiculous statements. Your sexual activities or lack of them are personal. You should keep them too yourself. Don't make public announcements of your virginity or share sexual details with anyone. That is where reputations come from. You tell a friend in confidence and they broadcast it too everyone who will listen. Soon everyone who even knows you, knows every detail of your private sexual life. When asked about your experience, just answer that's personal, I don't discuss that with anyone except my doctor.

There is nothing wrong with waiting until you're out of high school, or even later, in fact you'll probably be better off.

The only thing I suggest doing is having sex before marriage, how long before is up to you.

Three words, Good For You. There is absolutely NOTHING wrong with waiting till your out of high school, if you want to wait even longer, fine wait. Your body is your temple and it should be treated with dignity and respect. Since its your first time you should wait till you meet that special person, someone you feel a connection with. Its your body and only you can decide what to do with it. Don't let anyone tell you otherwise, if you want to wait then wait. When you meet someone and you tell them this and their not willing to wait, then forget them because once you give it up you want to feel that you truly have a special connection with the person. Don't pay any mind to what other people say do what feels right for you. And based on your response, I don't think you'll regret giving up virginity to what ever guy is lucky enough to be that person.

I waited and am glad. Ten years later I still can't believe some of the losers I dated in high school, and I'm so glad I didn't sleep with them.

i think that it's a good thing you're doing. :)
i also made this kind of commitment when I was in high school, and I think I had more fun throughout my 4 years there than my friends who were constantly dating. :P so many of my friends regret the way they lost their virginity and I didn't want to be like that. and don't worry if people label you as a virgin. you should be proud of it. I know I am proud about being one. :)

It's not at all wrong. Choosing when to have sex is a very personal decision, and entirely up to you. I think it shows your strength that you are abstaining from having sex until you are ready. And different people are ready at different ages. :)
