I mean, Ming-Ming has a Primarina named Amoré. Her entire theme is about love and romance. If you don't think those girls got up to their own sorta fun...
For the second part of the question, there was a Pallossand trap that managed to capture her and the rest of the party within its clutches, though it was defeated before it got her off. There's also a Charizard that emerged from a foothold trap... Instead of the dragon preying on an ally, instead Ming-Ming allowed herself to get plowed instead.
Who knows what that Charizard is up to now...
