The Sexplorer (US title: The Girl from Starship Venus, UK re-release title: Diary of a Space Virgin) is a 1975 British sex comedy film written and directed by Derek Ford and starring Monika Reingwald.

[2] A Venusian explorer, adopting the form of a human woman, visits planet Earth to study the behaviour and customs of Earthlings.

She meets and falls in love with a young man, and with him she discovers the pleasures of sex.

Monthly Film Bulletin said "The Sexplorer is meant to be funny as well as erotic, introducing an element of supposed self-parody through the person of its otherworldly sexologist and the 'bizarre' activity on which she turns a quizzical eye, whilst striving of course for the usual quota of titillation.

Unfortunately, as it is totally lacking in wit or style, the selfparody acts as a banana skin on which the film slips in its first minutes, falling flat on its face and remaining quite inert for the subsequent eighty minutes.
