That assumes the energy put in is greater than the energy lost to the wound, and that the pleasure itself doesn't incapacitate the target.

Plus, until they actually become incubi men can't feed directly on mamono mana for energy. Its noted in the settings that its common for men to fall unconscious from fatigue or pleasure during sex with monsters, at least until they become incubi, despite monsters infusing them with their mana to help them last longer. The same may apply outside of sex too.
