Anonymous1: Dick's own sexual preferences (monogamy, not heterosexuality, he was with Kory from before Jason entered the picture until after his death) aside, I have brothers, and I'm bi, and nothing like this happened. Then again, we didn't literally try to kill each other either.
Anonymous2: I always find it funny that everyone thinks Dick is a huge slut when his sex partners are still single digit is all. And he was always pretty clear how he felt about just fucking anyone.
Jason and Tim are even less experienced.
