Oral sex means to use the mouth and tongue to stimulate the other person’s genitals (sex organs). If a woman gives oral sex to a man it is called fellatio, and if a man gives oral sex to a woman it is called cunnilingus. Oral sex is as intimate as sexual intercourse, and can lead to STD infection. According to what the Bible teaches about sex, intimate acts like intercourse and oral sex should be kept for marriage. Not everyone who is married thinks this is natural or wants to have oral sex. It is never right to pressure someone to take part in sex acts if they don’t want to.
