my sun moon midpoint squares person b sun moon midpoint, 1 orb. my progressed sun conjuncts person b sun moon midpoint to 1 orb or near exact. (both on 16)
there is no aspect from person b to my sun moon midpoint, however, in the composite, there is an interesting thing (if its appropriate or meaningful i don't know) composite sun is conjunct person B (female) natal sun/moon midpoint.
the composite moon is conjunct my sun/moon midpoint (male me!)
just thought that was interesting, not sure if it has any meaning though.
both are tight (1 orb) conjuncts (composite to natal sun/moon midpoints)
the composite asc might also be right on my sun/moon midpoint.
