The answer is in this never-reprinted tale from Key's Weird Tales of the Future #6 (1953).
writer of this story is unknown, but the artist is Eugene E Hughes, who
had a brief career in comics working exclusively for Key Publications, then disappearing from the art world (comic books/strips/commercial art) entirely!
Here's a never-reprinted sci fi/horror tale from the 1950s...
...from a Weird Science/Tales from the Crypt clone!
Illustrated by Joe Sinnott (best known as the inker for a large part of the Fantastic Four's Silver and Bronze Age run), this tale from Atlas' Uncanny Tales #15 (1953) actually has a scientific basis (sort of) for the conclusion!
This Don Rico-written and illustrated tale from Fox's Fantastic Comics #7 (1940) might well be the first example of inter-species...er...relations with the female as the aggressor!
(The hot-to-trot one in such stories is usually the alien male!)
BTW, what happened to the Queen's father, whom she claimed was an Earthman?
How'd he get there in the early 1900s?
What happened to him?
Another example of the multiple concepts the amazing Rico just tossed off the top of his head, then promptly forgot about while working on these maniacally-paced stories!
