I'd say dragon, most is bara. But some people waifu that.
Truth be told, objectively speaking electric has no waifus. Some people may like ampharos and thubderdoggo, but those have no sex appeal to anybody other than degenerates like us. Every other type has at least one pokemon with a bit of appeal.
Fire has Delphox or braixen, poison has salazzle, fairy has florges, water has ptimarina, grass has roserade, psychic has gardevoir, dark has zoroark, steel has magearna, ghost has frosslass, bug has leavanny, flying has Lugia, ice has frosslass or Ninetales, fighting has Lucario and Machamp, etc.
