Wouldn't gay relationships have the potential to be much healthier than straight ones?

I was just thinking, and I wondered whether anyone has thought the same. Wouldn't gay relationships be healthier than straight ones in some cases, because both partners have bodies that work the same way, and while in straight relationships sometimes you need (so I've heard) "guy time" and "girl time", but you wouldn't need that because you're both much more similar, and are able to think in a way that's closer to the other than you would if they were the opposite gender?

/barely coherent

Irrelevant: Does that black and white flag with the rainbow "A" on it mean that you support LGBT (I always get mixed up with the G and the B) rights, but you are a straight gender binary? I don't want to be putting up flair that means something different to what I think it does.
