The phrase "Half and Half" is used in the prostitution industry to describe a package deal of services that begin with the prostitute first performing fellatio upon the customer and then engaging in actual copulation to completion. Some prostitutes narrow the selection of positions available in the intercourse segment to the missionary position or the cowgirl position.
This package is by far the most requested sexual service of in-call and out-call prostitutes (ie. non streetwalkers)1. "Reverse Half and Half," wherein the intercourse precedes the fellatio, is not nearly as popular.
