He would need to be in a state of spirit energy/demonic energy balance that is sufficient to turn him into an Incubus or his death is guaranteed since he CANNOT change.

Unless the girl is a Baphomet or Lilim, she just doesn't have the output to do it in one night. Most monster girls take months or years of 'practice' to get an individual man to that tipping point. But as I've noted elsewhere in here, if the smallest desire or momentary atrraction was enough to turn an Incubus into an Alp, there would be no Incubi, only Alps. Psychologically speaking, humans are a MESS of subconscious impulses with a mostly imaginary rationality overlaid on top -- we do things that are unequivocally insane, then rationalize it to the point we remember making reasoned decisions even though at the time we were not reasonable at all. Everyone man who can be trusted to dress himself has at least minor homosexual tendencies. You occasionally see men who have no such tendencies at all with terrible combovers and wearing suits that clash within their own pattern. But whether a man goes Incubus or Alp, according to MGE canon, is when a man is homosexual or gender dysphoric. But humans in MGE would have to be either mentally different enough from RL humans that they'd constitute an unrelated species that coincidentally has the same name, or it would take a LOT more than just the odd impulse to make an Alp instead of an Incubus. tl;dr No it wouldn't happen unless the man was destined to be an Alp instead of an Incubus anyway.
