Or, they might say, instead, that you are actually straight and just playing around with girl-on-girl until the perfect cock magically rescues you from inferior lez sex. Our culture, after all, has long revered the phallus. Thus, straight men fetishize bisexual women, fantasizing that, "If she just spent some time with my big boy, she'd never have a hankerin' to scissor again."
For my part, I've heard this more than once from my gay friends... "Oh, Rand. You're not bi. You're 100% gay. Just admit it!" Sometimes I wish they were right. At least there would be a community that accepts me. And, as you probably know, trying to juggle a mixed-orientation relationship ain't the least bit easy, nor is it easy to explain.
