In Every Woman Has a Fantasy, producer-writer Summer Brown (as Sandra Winters) and husband director-writer Edwin Brown (as Edwin Durrell), let the viewer into the inner sanctum of a group of women who meet weekly to discuss their lives and open up to one another about their sexual fantasies. Nancy Friday's My Secret Garden was published more than a decade before Every Woman Has a Fantasy was made, so I guess it was pretty well-accepted that many women had rich fantasy sex lives. The implication here, at least, was that it was still rare for them to open up about them, with friends, and especially partners.
When Ben (John Leslie) asks his wife, Teri (Rachel Ashley), if he knows any of the women in the group, she explains that the women not knowing each others' spouses is a benefit to opening up since there's no threat of the fantasies getting back to their husbands. Ben's fascination with the group turns to an obsession as he progresses from hearing the fantasies relayed by Teri to convincing her to smuggle in a tape recorder to hiding in the closet when she hosts the group to, finally, dressing in drag and posing as his visiting cousin, Jennifer, to sit in on a meeting.
