As others have said, Gambit isn't a sleaze. He's a flirt, a charming, handsome, charismatic, magnetic guy who COULD have a girl every night, that every woman kinda secretly wishes she could have a one off fling with, he's tall, dark, handsome, charming, but, not a louse. He's had very few confirmed partners, and all of them less problematic than almost any Cyclops or Wolverine have had. Who would his most problematic one be? Candra? I suppose Genevieve? He's a guy who married his high school sweetheart Belladonna, and only left her to prevent a war, had very few confirmed sexual trysts, and then dated Rogue for years. He's a charmer, not a louse.
