first and foremst you are too young to be thinking about a baby. Do not let him convince you to have unprotected sex either. Please have him use a condom if you must have sex. When you are young it is soo easy to be mislead by selfish people. EX. this boy.
If he says stupid stuff like I want to have sex with you without the condom that is just selfish and uncool. He also sounds like he has an insecurity problem. Almost like he needs this baby for you to stay with him. Tell him you can still be with him and you do not need to have a baby to prove your love to him. Please use some type of protection. Do not spend the rest of your life regretting your HIV or Herpes or any other sexual disease or worse AIDS.
Ask mom or an aunt to take you to get birth control. Talk to a older family member if you are not comfortable talking to your mom. Enjoy your youth it only comes once.
