Yes! Because sperm is alive in a wet enviorment it can survive, thats why you should use condoms and keep sperm away from you vaginal area if you dont want to get pregnant. You should test in a few weeks or go to a doctor

Yes. If you are having sex without a condom, you can get pregnant from pre-ejaculate ("precum"). Pre-ejaculate is fluid released from the penis which can be made of some sperm and semen, men cannot control it, and it clears the urethra of any acid build up from urine so that the sperm have a better chance of surviving. Some sperm can be in the pre-ejaculate fluid.

Pulling out or withdrawal is not a method of birth control. If you are relatively young (under 18) and continue having sex without protection for a full year, you have a 90% chance of becomming pregnant even if he is pulling out.

My suggestion, if you do not wish to become pregnant, would be to go to your doctor or local family planning clinic and request a reliable form of birth control. Again, depending on your age and your state, you may have to have a parents consent to obtain the pill or the shot or the patch, etc. anyone can buy condoms at any time, there are no laws barring people under the age of 18 buying condoms. My advice would be to get on the pill or another effective method and also use condoms to prevent disease or infection.

If you need anything else, pm me.
