Yeah Bianca kissed him in the movie "Pokemon heroes" and Melody also kissed Ash in "Pokemon 2000"!! :D
Melody gave him a welcome kiss and also, Jesse and James welcome kisses him in an episode from season 1!!
That was funny! XD
Sorry for the guy who commented above AninditaS, but "kiss under the mistletoe" was simply a fake rumor. It was the same with AshxMay. All just stupid rumors. Take it from a guy who actually watch Pokemon in both Japanese and English and has Japanese pokemon fans. Kiss under the mistletoe is just a fake rumor. Deal with it.
Okay If u wanted to be technical Melody WAS his first kiss but it was cheek not lips. And about the whole Latias Bianca mix up on Pokemon Heros I big part of me wants to say Latias for the way she walked her arms kinda out to her sides and how she moved her legs. I also heard that the director said it was in fact Bianca, but I have only heard it once so I won't believe that till I've heard it at least 5 other times from different people! Some people say it was Bianca because after ash and co. leave the dock you see Latias, but NEWSFLASH! LATIAS CAN CHANGE FORM IN THE BLINK OF AN EYE IF SHE WATED!! Other people say it's Bianca because she left her hat on the table in her apartment and that the picture was done by Bianca npt Latias because Latias is a pokemon but here's what I say, What IF Latias got Bianca to draw the picture for her and took the picture to Ash. So really it could go either way. Use what ever way works for you! I say it was Latias because I think LatiasxAsh is cute :3
OK in Pokemon hero's it was latias who kissed ash because through out the movie you could only tell Bianca and latias apart from Bianca hat she always had her hat. but that's my opinion some people think its was Bianca because it showed her hat hanging on the chair so really we will never know its just one of the many mysteries of Pokemon.
In the movie pokemon heros: latias and latios bianca (or latias transformed to bianca) kissed ash
jessie and james also kissed ash in some point
melody kissed ash in the movie the power of one
and i'm pretty sure misty kissed ash in a banned episode
