okay have sex wherever you want but this will be your life if you make the slightest mistake.
he will bang your brains out.
Some **** will go wrong and you'd either get aids, herpes or get pregnant. Let's just say you do get pregnant.
He will dump you and the baby.
You will have to tell your parents what happened (that never ends well).
You will be made fun of at school and being called a slut and all that etc.
You won't be able to take care of the baby on your own so you'll have to live with your parents for a long time.
You won't get another boyfriend or get married because well you have a baby (if not a sexually transmitted disease that won't kill you so you'll be lucky to be alive by this point!)
You'll be too busy with the baby that your education will go down the drain with all your hopes and dreams.
In summary if something goes wrong your either gonna die, get itchy or f*** up your life. What ever decision you take...Have fun! :)
