Forrester returned again and again for 15 photo shoots during the next 14 years, using the stage name Forrester Millard. Bob sold the photos by mail order through his company, the Athletic Model Guild, and, beginning in 1951, Physique Pictorial, the first magazine aimed at a gay male audience (although it claimed to be for fitness enthusiasts).
Branching out, Forrester became the "mascot" for the Table of Contents of Tomorrow's Man beginning in 1954.
In 1960 Forrester left Los Angeles and retired from modeling. Eventually he married Barbara, and they had a son, Forrester Jr. They lived in Rochester, Washington, near Olympia, for thirty years.
He died in 2011.
There are nude photos on Tales of West Hollywood.
