Just stop and think for a minute.
What would happen if you got pregnant?
A 14 year old can't support a baby.
And you don't really want to dump it all on your parents do you?
I'm not going to say 'No! Your wayyy to young! Keep your legs closed!'
But if you do decide you have sex, get on birth control at least a month, if not 2 before you do. And use a condom.
