I just saw a post saying that sometimes people click out of a fic if their fave is suddenly good in bed asdfghjkl and it got me to think if we were to take les mis super realistically, Enjolras would be bad at sex. He's uninterested in it, maybe even sex-repulsed but if we were to assume he's explicitly celibate by choice and not by temperament, he's still a huge virgin who does not engage in the whole exercise
But! If we take les mis as intended with it's fantastical supernatural elements and the narrative symbolism, Enjolras would be so divinely good at sex that he would maybe cause people to orgasm so hard they go blind.
And he wouldn't even do anything special is the thing! He'd be like that bit at the end of the Arras trial where the public is in such awe of Jean Valjean that they let him leave, you know?
Enjolras could do everything wrong but it would be good because symbolically it only makes sense for it to be like that
