Franklin D. Roosevelt and his wife Eleanor had six kids, born from 1906-1916. He was stricken with polio (or some other paralyzing illness; there’s still some debate, acc. to his Wikipedia article) in 1921. FDR is generally acknowledged as having had a longterm romance with Eleanor’s onetime social secretary Lucy Mercer (later Lucy Rutherfurd, after she married), beginning sometime in 1914, which continued off and on for years. Rutherfurd was with the President when he died in 1945.
Call it morbid curiosity. Was FDR capable of sexual intercourse after becoming paralyzed? Do we know, or can we only guess?
While poliomyelitis used to be called “infantile paralysis,” it is not in fact a paralysis in the sense that a spinal cord injury is, but a disease that degenerates the muscles/their innervation, leaving one with atrophied limbs, etc. FDR could walk haltingly with braces, usually escorted by someone on whom he could put some of his weight, but his leg muscles were so far atrophied and the sheaths of their nerves so badly damaged that it was a truly major effort for him to do so.
Remember too that the innervation for the sexual apparatus is “on a different circuit” and is quite functional even in true paraplegics. Probably FDR had no problem getting an erection and sexual pleasure, although he likely could not use the missionary position owing to leg weakness.
