Lack of access to sexuality information - and the power of sexual shame - prevent Americans from making informed ethical choices about sexuality. This is an impediment to freedom in almost every aspect of life and so we work for an American culture which respects individuals' needs to freely inquire, discuss, and debate sexual issues. The Center for Humane Sexual Culture works with the public to ensure access to sexuality information of all kinds.

I think this student at Columbia nails it about sexual shame–rah! Here’s the last paragraph, which oughta start his eventual dissertation, if you ask me 
From Eliot Spitzer to a teenager coming out as queer, our inability to deal with sexuality can alter the course of lives. The very notion of a gay pride parade illuminates the deep sexual shame which makes it necessary. While Disney will probably dominate Times Square for many years to come, we each have the individual power to create strong, open, informed, publicly accessible, and wild sexual spaces. A constant intellectual discourse and discussion of sexuality and sexual acts, along with a vigorous engagement in diverse and enjoyable sex, can only lead to a more fulfilling world.
