There are so many ways to mix the two signs, I think it always depends. I have an 8H Pisces moon on the solstice point of 3H Libra Pluto (.04 orb, I think.)
This creates a kind of resonance and tension between my private thoughts and public expression. As you see, my Libra and Pisces are joined through a Pluto "link" so there is a depth here not consistent with "girly girls."
Though, femininity and depth are not mutually exclusive. Not at all.
I think anyone who knows me on this site has seen me being very compassionate at times and taking a hard line at other times. But to me, it's not like I shift between male/female expression...
More like, in general, I try and strike a balance: always hoping or working for the triumph of principle (Libra) while reconciling everything through acceptance (Pisces)...and that's a gender-neutral kind of approach.
