If you are ready for sex, you also have to ready to provide contraception, be able to tell you
parents, and to talk to your partner about it on an adult level.
Sex is the best, when the time is right. At 13, the time is not right, for anyone. I would concentrate on your friends, school, sports and other interests that will not leave you sick, ashamed or a father at 13 years old. All those things really do happen.
Enjoy your youth, it only lasts so long, and then it is over forever.
