My ex is hetero. We're not together but we have sex. Lately we've been spending more time together, and he seems pretty proud when people think we're a gay couple. It adds to his liberal cred or something. He said he tried to be gay or bisexual for years, and just couldn't manage to get it up for a man.
So yeah. He's gynephilic, but I'm more masculine than he is, and our gender roles were always blurry. And he wants to be seen as very open and wordly.
In a sense, I feed into his affectations, but I also have fun and give him experience.
Things get into grey areas, you know?
