Uterus Also known as the womb, the uterus is the pear-shaped, muscular reproductive organ in women that is responsible for menstruation and pregnancy.
Vaginal Contraceptive Film (VCF) This is a form of birth control used by women; a very thin square that dissolves quickly in the vagina and releases a spermicide that kills sperm.
Vaginal sex Sexual activity where the penis enters the vagina.
This is the act of pulling the penis out of the vagina before ejaculation occurs in order to prevent pregnancy. It is also known as 'pulling out.' Withdrawal offers no protection against STIs - including HIV/AIDS. Pre-ejaculate does contain semen and bacteria. So if two people are having vaginal sex without using a condom, the woman can still get pregnant and either partner can still get an STI.
Yeast is a very common fungus that lives in small amounts in a woman's vagina. If too much yeast grows it can cause itching, burning, a white discharge and painful sex. Men can also experience symptoms of a yeast infection, but it's rare.
