Now that I have your attention... Let's start with this: what is sex for?
I think it's fair to observe that we livie in a culture that tells us that sexual expression and fulfillment are necessary condition of both personal identity and of a full and complete life: I cannot be fully and truly who am I without the freedom to express my sexuality in whatever ways seem best to me (as long as there is no harm or coercion involved). Whether we want to talk about marriage, hook-up culture, friends-with-privileges, affirmation of and support for GLBTTQQ (gay, lesbian, bisexual, transgender, transsexual, queer, questioning) neighbors, pornography, masturbation, and wherever else we might want to go, issues (and questions) around sexuality are at the core of the conversation. So: what is sex for? The amazing pleasure it can bring to me and my partner, or partners? As the ultimate expression of love and commitment--or are love and commitment no longer a necessary part of our various sexual equations? Is my sexuality a purely private matter, or does what I do in my bedroom (or wherever!) have any impact on my neighbors? And what do I do when I'm so horny I just can't stand it?
