Hey...
Hows it goin? If you don't want to get her pregnant, I would strongly advise you to either have her get on birth control, or think again about sex. Condoms work most of the time, but they can be unreliable. Birth control is the best way to assure that she won't get pregnant next to abstinence. She can get birth control confidentially if she goes to a planned parenthood place somewhere like that. There should be one close to you. They can cover the cost of birth control if that is a problem. But pulling out is definitely not a very good way of preventing pregnancy as pre-cum does have the capability of causing pregnancy. I hope this helps. Let me know if you have any more questions. I would be happy to help! :) have a good one.

The first reply is correct! The pull-out method is unreliable because the pre-cum does have sperm in it. This is how my brother was conceived!
She is probably not pregnant from just this one time, since you did use a condom the first time and was only inside of her for a minute the second time. So I wouldn't worry too much! Just use protection in the future.
I just want to warn you that in most of the us, sex with anyone under 16 is statutory rape - in some states, it is under 17 or 18. So be careful!
