How did William Moulton Marston explain the bondage scenes in Wonder Woman comics?

William Moulton Marston, the creator of Wonder Woman, defended the frequent bondage scenes in the comics by claiming they were allusions to suffragist imagery.1

However, this explanation has been noted by critics and historians as straining credibility. The prevalence of these scenes is widely viewed as reflecting Marston’s personal philosophy of "loving submission" to authority, a concept that was pervasive throughout both his comic book work and his private life. In his earlier psychological writings, such as Emotions of Normal People, Marston argued that sexual desires related to dominance and submission were natural products of the nervous system and should not be considered taboo.12
