To be fair to MaxCherry, the scenes that would have proved conclusively that Woodward's character (Sergeant Neil Howie) was a virgin were cut from the version of The Wicker Man that most people have seen. From what is left, we know that Sergeant Howie is prudish, extremely puritanical, and emotionally and physically uncomfortable with any talk of sex, fertility and/or procreation.
It's left to the audience to assume that he has never had sex, which, I must say, was not a judgment I found too hard to make when I first watched the film.
