Not any and every conversation, no.
If I want to talk to about motherhood, I'll talk to mothers of whatever background, race, religion, nationality, etc.
If I want to ask about fatherhood, I'll talk to fathers of whatever background, race, religion, nationality, etc.
If I want to discuss parenthood, I'll talk to parents of whatever sex, background, race, religion, nationality, etc.
Diversity of conversation doesn't automatically require a male voice or perspective and in a number of conversations does the exact opposite of enriching the dialogue.
