I have really never had a problem with this, but would be interested to hear from others as well. Our male Dobie lives with two other male dogs at the moment and has had no issues. He hasn't ever shown distaste to males outside of our home either. I attribute that in part to the fact that he simply knows better, that fighting is not tolerated, and part to the fact that he comes from very even tempered lines.

I suppose there are Dobermans who work differently, but again I think that would be a dog specific, not breed specific thing. I've seen gender agression in anything from Pomeranians to GSDs. Thoughts?
