Maybe. I thought it was more of his usual of dodging responsibility. When Chris the Goddess is present, everyone pelts him with questions about the Merge, etc. because he's the principle source. As Mewtwo and Sonichu, all he needs to do is say "Nyeh, stop being mean to Mama, she's very Busy right now!" while not even bothering to alter his behavior.
He's always had a bizarre relationship with his own masculinity, though. A lot of hate/rejection + a staunch refusal to completely let go of his bent duck (unless he's recently gone full vagina without my knowledge lol). I definitely see where you're coming from, here.
