4) If you douch right after sex, you won't get pregnant.
Douching, which is a product use to "cleanse" the vaginal area, will not work to prevent pregnancy. It actually pushes the sperm into the uterus faster from the pressure of the fluid.
5) If a guy pulls out before he ejaculates, the girl can't get pregnant.
This will not work because of something called pre-ejaculate, or precum. The fluid is released before a man ejaculates and he can not feel it. It also has the highest concentration of sperm, which could increase her chances of becoming pregnant.
6) There are no dangers from oral sex.
Many STDs are passed through oral sex. Anytime contact is made with another person's genital area and/or fluids from those areas, the chances of spreading an STD is very possible.
