The guy I was with told me that there are certain positions in which you wont get pregnant if he pulls out first is this true?
No, this is not true. Getting pregnant has nothing to do with what position you have sex in. Pregnancy can happen when semen gets in the vagina or on the vulva.
Withdrawal, also known as pulling out, prevents pregnancy by keeping sperm out of the vagina. Pregnancy cannot happen if there is no sperm present. A man who uses withdrawal will pull his penis out of the vagina before ejaculation — the moment when semen spurts out of his penis.
The withdrawal method is not recommended for teens for several reasons. Many young men lack the experience and self-control to pull out in time. Some guys have been known to say they will pull out, and then they get so excited and carried away that they don’t. Some guys cannot tell when they’re going to ejaculate. Some guys ejaculate very quickly, before they realize it. And younger men are more likely to have more than one ejaculation a day, either through masturbation or sex with a partner. This increases the chance that live sperm are in the system when pre-ejaculate oozes from the penis.
Also, both ejaculate and pre-ejaculate can carry sexually transmitted infections, such as gonorrhea, chlamydia, and HIV. Latex and female condoms reduce the risk of unintended pregnancy and sexually transmitted infections.
