That merely implies that ENTP personality characteristics are more "masculine" (if we go by traditional societal definitions of "masculine" and "feminine"). I still don't see any reason to believe that female XXXXs are different from male XXXXs simply because of the difference in gender.
If I would add a letter to further distinguish between the types, it would probably be masculine/feminine. Gender makes you different.
Yeah, if my boyfriend had to say, his favorite out of my friends is my ISFP probably. Although he gets sort of annoyed with her because she never understands his jokes and she thinks he's weird.
Yeah. There's a big difference in sense of humor. They seem to either miss or misinterpret a lot of my jokes. I think it's easier for them to make me laugh than the other way around. They laugh most when I'm just acting totally silly, which is a frequent mode with me.
