I don't know about all of this...if the male-male contact is incidental then why would that make it gay? The goal with DPs is usually to push the whore to her limits or degradation, both guys (again, usually) are in it solely to fuck the ever-loving shit outta the chick, not each other.
Being gay is in your head and about who you desire sexually, so if two guys double team a whore because SHE turns them on, then I don't consider that gay. Now if one (or both) of the guys are more in it to feel the other dude's balls then yes, that would be a gay act.
DP in the same hole...yeah, that's a little more gay, but still if the dudes are aroused by the whore and not each other, technically it's not gay. Sure, there are probably a lot of folks in denial that use sexual situations like these to express their bottled up "gayness", but I don't think that's always the case. If so, anyone who's ever been to a urologist, had their dick pierced, or has had their prostate checked is now officially gay.
Just one opinion.
