Sex organ
Apart from the man putting his penis into the woman's vagina, the sex organs can be used in other ways in sexual intercourse. The man and woman can rub each other's sex organs with their hands. They can use sex toys such as dildos or vibrators. They can also engage in oral sex. When a person uses his or her mouth, lips, and tongue to touch a woman's clitoris and vulva, this is called cunnilingus. When a person uses his or her mouth, lips, and/or tongue to touch a man's penis, this is called fellatio. A man or a woman (using a strap-on dildo or harness) can also put the sexual organ into a person's anus, this is called anal sex.
