I'd say that it could be something dissociative that you're experiencing. Have you ever switched (another alter fronting, yourself stepping back inside)? It's possible to have DID even though you're not switching (that's what I've been told), only experiencing the alters and dissociative things on the inside (not showing on the outside, for outside people).

You don't have to lose time in order to have DID - you can be co-conscious with your alters, which means that you're "with them" fronting, or experiencing the outside world with them (which I guess is what you're describing about a male voice telling you that a child part wanted to play etc).

I hope you can figure things out. My advice for you would be to start looking further into DID, getting to know your alters and learn from others who are multiple. That's how I learned what I know today about myself and my alters.
