Heavy petting
Heavy petting means to caress or stimulate each other sexually, using the hands or other parts of the body but without the penis being inside the vagina. Heavy petting leads to sexual arousal just like sexual intercourse, and is actually foreplay. It can be very hard not to go on to intercourse when you stimulate each other in this way. Touching each other’s genitals is a kind of sex, similar to intercourse and oral sex, and you should wait till you are married before you do this.
