Preventing Pregnancy:
http://www.plannedparenthood.org/TEENISSUES/BCCHOICES/BCCHOICES.HTML

Questions to ask when deciding on a birth control:
-How will it fit into your life style?
-How effective will it be?
-How safe will it be?
-How affordable will it be?
-How reversible will it be?
-Will it protect against sexually transsmitted infections?

Four methods not usually suggested for teens:
-Sterilization effectiveness: 99.5 - 999.9%
-The IUD (Intrauterine Device) effectivveness: 98 - 99.4%
-Withdrawal effectiveness: 81 - 96%
-Periodic Abstinence or Fertility Awareeness Methods (FAMs) effectiveness: 75 - 99%

Why not use those prevention devises?
-Sterilization: This method is intendedd to be permanent. It is not appropriate for anyone who may want to have a child in the future. Because people so often change their minds about having families, sterilization is usually discouraged for people under 30 who have not had children.
-The IUD: *Unless she has had a child,  a young woman's uterus may be too small to hold an IUD. *IUD users who get certain sexually transmitted infections can develop pelvic inflammatory disease and become unable to have children. Teenagers are at very high risk for these infections. One out of four teenagers has a least one of these infections.
-Withdrawal: *Some men lack the experieence and self-control to pull out in time. *Some men have been known to say they will pull out, and then they get so excited and carried away that they don't. *Some men cannot tell when they are going to ejaculate. *Some men ejaculate very quickly, before they realize it. *Before ejaculation, almost all penises leak fluid that can cause pregnancy. 
-FAMs: *These methods work best for wommen with very regular periods. *Teen women often have irregular periods. *Their partners may not wish to cooperate in using this method. *A teen's relationship may not be as stable or as committed as is necessary for developing the trust and cooperation necessary for effective use of this method.

Things to remember:
1. Thinking "it won't happen to me" is stupid; if you don't protect yourself, it probably will. Sex is serious. Make a plan. 
2. Just because you think "everyone is doing it," doesn't mean they are. Some are, some aren't - and some are lying. 
3. There are a lot of good reasons to say "no, not yet." Protecting your feelings is one of them. 
4. You're in charge of your own life. Don't let anyone pressure you into having sex. 
5. You can always say "no" - even if you've said "yes" before. 
6. Carrying a condom is just being smart - it doesn't mean you're pushy or easy. 
7. If you think birth control "ruins the mood," consider what a pregnancy test will do to it. 
8. If you're drunk or high, you can't make good decisions about sex. Don't do something you might not remember or might really regret. 
9. Sex won't make him yours, and a baby won't make him stay. 
10. Not ready to be someone's father? It's simple: Use protection every time or don't have sex.
