Gay Beefcake in magazines started out with posing straps still being commonplace. But as the 1960s wore on the publishers kept pushing the envelope with homoerotic themes or nudity. It wasn't until 1966 that male full frontal nudity became legal on magazine covers. After that most magazines ended up dropping their posing straps by the end of the decade. The late sixties also saw an explosion of hardcore gay sex magazines that tied in with the Sexual Revolution.
