LOL... sounds like you know your chart very well!! Not considering the degrees, just whole signs (used a lot in Classical/Hellenistic Astrology) - your Venus and Mars are squaring (both fixed signs). Quite the combination! How do you experience it?
I think a mainstream interpretation wld be the obvious relationship issues; but perhaps it can signify the growth needed in the area of compromising "self individualization" with 'relating, social, getting along" affairs... is Venus right on your ascendant? Mars in the 4th? Part of your individualization purpose is about finding your values, self love, worth... all that wonderful stuff. It's also a simple survival lesson. Mars there may make you feel like you've needed to "fight" for your survival.
And yes, all this Earth makes your body naturally "keep" and unfortunately, a Pisces Mars... well, doesn't force itself TOO much - just that planet alone, not counting aspects or anything!
My entire chart is WATER, FIRE... almost everything in Pisces... and what's not in Pisces is in Sag... but, in the 12th house, ruled by Jupiter in Pisces... oh my!
Just a thought!! xoxo
Love, Light & Kisses!
