The guilt is even stronger since I wound up finding (and marrying) a partner who happened to be male, so I to all intents and purposes look pretty much like a happy het. I'm not; it's really a matter of timing and coincidence that my partner turned out male. But by loving the person that I do, I often feel like I'm not doing my part to support GLBT rights. (Not, mind you, that I'm going to drop him to go find a cause-acceptable female.)

*frantic waving*

YES. THIS. SO MUCH THIS.

Hi. I'm in the same position and I feel exactly the same. Thank you so much for putting it so eloquently!
