This can be defined as sex play without vaginal intercourse. It includes body rubbing and mutual masturbation. 

This method allows for sexual pleasure and is nearly 100% effective against pregnancy if ejaculate or pre-ejaculate isn’t spilled in the vagina. 

Most methods of outercourse also carry no risk of sexually transmitted infections/HIV transmission. 

However, if partners engage in unprotected oral or anal sex, STIs and HIV can be transmitted. 

Outercourse requires commitment and self-control from both partners, as well as good communication between partners. 

Couples engaging only in sexual outercourse should also be aware of methods of contraception that can be used with intercourse so that they can be prepared if they decide the engage in sexual intercourse in the future.
