I have always loved reading romances about gay men. I have thought a lot about why it turns me on since, in my experiences, its not something straight women talk openly, and for a long time I felt like I should keep my feelings quiet for fear of censure.
I think the cognitive and emotional thrill comes from reading about two men expressing their love for each other in a way you don't often hear verbally. I think what I mean by that is, a gay male author might write a story that is full of incredible romanticism and incredibly expressive and eloquent, but, as a man (without the author's hat on) may not express these things to his actual partner as openly. In my experience, many men have a problem communicating their emotions, both gay and straight. I have a very happy marriage and I am very much in love with my husband, but we often struggle with maintaining open communication and me feeling like he isn't talking to me about things, or hearing what I have to say. Often in these romances, the characters have the same struggle, but you hear the thoughts in their head and see them work to put it in the open.
I am also sexually thrilled by the thought of two men together and look forward to reading these scenes. There could be lots of different reasons for this. A friend of mine (who happens to be a lesbian, with no attraction to males) said that maybe its because its illicit, that women are turned on because its different from what they have experienced. I think the larger part of it is, that I am wholly turned on by men (I have no real attraction to woman, although I can tell you when I think one is beautiful or not). Everything about the male form turns me on. Two males is just double that.
Anyways, I enjoy the community here and offering my support for the GLBT community, as I often do out in the world. I look forward to (and often obsess about) the story updates at GA. I look for certain people's comments in threads and keep any eye on blogs, because the people here are interesting. They make me want to know more about them and hear what they have to say.
This seems to be rambling and if you ask me to clarify anything I said, I will be happy to try.
