"(Reuters Health) - Domestic violence occurs as much and possibly more among same-sex couples as among opposite-sex couples, according to a fresh look at past research.
The study team can’t say why domestic violence may be more common among same-sex couples, but they suggest it may result from the added stress of being a sexual minority.
“There are vulnerabilities that come with being in a homosexual relationship,” Richard Carroll told Reuters Health. “It can be as basic as someone not ready or willing to be open to their family or community that they’re in a homosexual relationship. The theory is that additional stressors can add to increased strain that leads to increased violence or abuse.”"

So the primary theory is that the added stress of societal judgment regarding same-sex couples leads to this. Perhaps though this might also stem from violence occurring at a more "even-footing" if it could be said. Personally if I was in a relationship with another man we'd get into fisticuffs now and then regarding arguments. Of course that's really all just straight out of my ass, just a thought.
