well for me i dont really think its right for any girl or guy to be having sex under the age of 18 because they are immature. Even some 20 year olds are just as immature.
And the thing is when you get pregnant in high school you have pretty much screwed your life up. You now have to take care of yourself and your child.
And if you do have sex early then thats on you if you get pregnant though dont be running to mommy and daddy to bail you out on it. you wanted to have sex so you must think that you are ready to have a baby. Deal with it. Get a job and raise your child.
