Some months ago, during one of the periodic Lord of the Rings discussions hereabouts, it occurred to me that Aragorn son of Arathorn was probably a virgin until his wedding night. Or possibly it occurred to Elendil’s Heir and I just agreed; I don’t remember. That would mean that Aragorn was chronologically in his 80s (though physiologically probably in his 30s) when first he made the two-backed beast.
Back in the 90s, I remember it being made explicit on Lois & Clark that the Last on of Krypton, being a romantic and a Boy Scout, had been saving himself, if not for marriage, at least for the woman he would fall in love with and commit to marrying, and so his first time at bat was in his mid-20s with a certain snoopy reporter chick.
And my baby sister always claimed that Wonder Woman was a virgin. Well, a heterosexual virgin, anyway.
What other fictional characters kept their virginity to an atypically late age?
Aragorn was raised in Rivendell by elves, and thus probably had an elvish view of sexual morality. The Elves considered voluntary sex pretty much equivalent to marriage. Aragorn would not have considered himself betrothed to Arwen if he’d ever had sex with her (or anyone else); he’d have considered himself married to her.
In “The Sign of Four”, Watson claims to have had experience spanning many nations and three different continents, so definitely not him. I’d suspect neither Sherlock or Mycroft ever got around to having sex at all.
In Sherlock’s case, there is a school of thought among some Sherlockians that during his hiatus he got together again with Irene Adler and had a child, supposedly an ancestor of Nero Wolfe. According to noted Sherlockian William S. Baring-Gould, he would have been 37 at the time.
How about Ms. Marple? She was never married, and is from a time period before sexual liberation was common. Possibly a closet lesbian, but I’ve never seen any indication of that. At the time of the story “At Bertram’s Hotel” she is in her early 70s.
