He and Burt Ward, his co-star who played Robin, would have "quickies" with women between scenes and while in costume.
The actor said, years after the show: "Because of the physical limitations of the costume, you gotta have quickies." Offset, his sex life appeared even wilder.
West reportedly became a regular at orgies. Once, he and his friend and co-star Frank Gorshin - who played the villain, The Riddler - were banned from an orgy because they were mimicking the characters they played on television.
West said: "We walked in and it was an orgy. So I immediately went into the Batman character, and Frank went into the Riddler character, because we were getting the big giggles.
"It was so funny to us, what we walked into. And we were kicked out. We were expelled from the orgy."
West, who was twice divorced by the time he took on the iconic role, dated actresses including sisters Natalie and Lana Wood, a former Bond girl.
After the ABC show ended in 1968, West struggled with being typecast and had a hard time finding consistent work.
His personal life became more tame and he married his third wife, Marcelle Tagand Lear, in 1970. The pair had four children.
The star was married three times, and had six children. He had homes in Los Angeles and Palm Springs, but he and Lear spent most of their time at their ranch near Sun Valley, Idaho.
