I think those who think it girly (your DH and some on this board) are reading that busy circle print (which I like!) as "flowery". I think to some people prints of any kind are girly. (Stripes, on the other hand, are masculine). Not suggesting you do this, but I'm guessing that if this quilt in these colors were all solids, no one would declare it girly.
Whatever the decision on its gender identification, it's a beautiful quilt!
