Having sex DOES NOT make you grow and become bigger. Your size and development are determined by hormones, family genes and body weight. Sex cannot make you mature faster, so delay sex until you feel ready for it and are in a trusting relationship where both you and your partner are ready for sex. You can get pregnant, HIV/AIDS and other infections from oral, vaginal and anal sex, so test with your partner and use condoms EVERY TIME.
