There are physical changes an Incubus would undergo. With only one possible exception though, none of the changes would make him look anything other than human. MGE Incubi are human men who have mostly internal changes to make them better mates for monsters. Where any monster has enough sexual stamina to drive any human man into unconsciousness from exhaustion, an Incubus gains enough stamina to do that to a monster. Probably more than one depending on his exact power level. Human men can be scrawny, underfed, fat, etc. Incubi get too much exercise for that. Instead of weight lifting, think wife lifting. Human men can get sick. Incubi are immune to diseases. Human men usually live less than 100 years. An Incubus life expectancy is matched to that of his monster wife's. Human men produce the spirit energy monsters eat just by being alive. A monster can feed on a human just by hugging one or living in the same house but the transfer rate is slow. The optimum transfer medium is semen. An Incubus changes to produce more spirit energy and more semen, both of which are internal changes.

A monster taking too much spirit energy from a man can render him unconscious or even drive him into a coma. Incubi can't run out of energy this way. About the only visible physical change is penis size. There are no poorly hung Incubi. This increase in size is the only change an Incubus undergoes that someone could point to as being even remotely abnormal about his appearance.
