There was a pre-teen comedy called 'Lil Darlings'. It starred Tatum O'Neal and Kristy McNichol. It was about a contest between them of who'd lose their virginity first. Beyond the Door 3 has a similar situation. Some teens crash the party of some Satan worshipers and find out that their virginity is the missing ingredient in their Master Plan. It becomes a race of who will catch the virgin first.
