INFJ Male And Females Different?

This is my first thread to start here on Reddit. I'm wondering if there's a difference between male and female INFJ's. INFJ females are supposed to be more common in numbers than males by quite a bit. There are four women I know of who tell me that they've taken the test and turned out as INFJ for them. I don't know any male INFJ's personally, although there may have been a couple I knew that might have been.

Is there a difference between male and female INFJ's? If so, what is an example on how they're different? The four women I know seem different than what I think of myself. These women seem more outgoing and have more friends than me, except for one. That's one example of why I think male and female INFJ's might be different.
