"Pulling out before the man ejaculates, known as the withdrawal method, is not a foolproof method for birth control. Some ejaculate (fluid that contains sperm) may be released before the man actually climaxes. In addition, some men may not have the willpower or be able to withdraw in time."

"No! you should never use more than one condom. Using two condoms sometimes called “double bagging” actually offers less protection than using just one because it may cause friction between them, weakening the material and increasing the chance that the condoms might break put you at risk of acquiring an STI/STD and unplanned pregnancy. No other method of birth control is as successful at protecting you against STIs and STDs as a condom. So always use a condom during sexual intercourse. But just one at a time!"

"No. Using condoms decreases your risk of getting HIV, Chlamydia, Gonorrhea, and Trichomoniasis. Since condoms don’t cover all skin surfaces they are less likely to protect you from diseases spread by skin-to-skin contact (e.g. Herpes, Genital Warts)."
