I'm still not believing that DD is gay. Having feelings for one person of the same sex does not make you gay. Yes I'm reading too much into it, but she never gave any more evidence that he had any other relationships with men after having feelings for Grindlewald. If she'd say something to that affect, then yes, I'd have no problems with saying DD is gay. Until then, he's not. Just flexible, life every other human being.
Oh and Jamie, WILL YOU BRUSH YOUR HAIR PLEASE?????
