I was not who you describe, being bi and going to full-on gay. So i'm going to ignore that part of your question.
But regarding your statement that the female drama is killing you, here's what I have to say:
Doesn't matter if it's a gay relationship, or a straight relationship, a RELATIONSHIP is work. There are some that are more work than others, but they all involve a component that feels like work. My relationship is a gay one.
The ones I've seen nearly always have a balance of energy between the people. One person is laid back, the other might be more demanding, or they're both fairly even-keel and don't really set each other off, and usually agree with each other.
I think the key to an absence of drama in a relationship, either with a guy or girl, is very clear communication and general agreement on the important principles that govern life. Everything else that helps define us falls away into the "personal characterstics that make up you" category.
In my relationship, there were periods that were drama-free, but then, more recently, there have been times that are insanely dramatic and I truthfully loathe those moments because it feels like both of us are straying away from who we really are, just to "be right" or prove a point. BUT, once we've both calmed down, generally, we come back to those core points on which we both agree. Were it not for those, we would not be together. This should hold true for being with a girl OR a guy.
I take your question to really be: is it easier to be with a guy than a girl? And I don't think it's easier either way. They both have their pluses and minuses.
