I think that altho I myself might not be an active participant in this, I would have to say that the type of DB BJ ever considered would have to fall along the lines of standing on one side and the girl in the middle and someone else on the other and let the girl suck one at a time.
Being intertwined like the majority of the DB BJ does not fall under any interest to me as the gender is not the one I would be willingly intertwined with. Nothing phobic, just a declaration of what gender this would appeal to me.
