If you had one thing to tell yourself as a teenager what would of it been?
I would have said Focus on your happiness do what makes you happy, don't do things to make everyone else happy. Focus on yourself yoga, doing things that make you happy, have an education, Don't believe everything boys or men say believe through background check, actions and words, and trusting yourself also value opinions of family friends if they all say something they might have known the guys reputation and seen something from outside perspective. Men are not important at this age, wait until the men mature when its time you'll know
If you have sex use a condom every time. Get that person checked physically for HPV genital warts, herpes also use condoms even after blood test, urine test, swab test research the HPV vaccine if you get it make sure you do all three don't miss one before having sex
