Psychological and physiological are obvious inexplicably mixed, but no i meant physiological, at least to a greater degree. I'm attempting to (if it's possible) find inherent value in accordance with humanities needs in this regard; to take the question beyond the individualistic nature of moral defection and to explore the idea of intrinsic value with regards to our sexuality in humanity. Whether or not, as the 'moral defect' the philosophers describe, has an inherent value, or an inherent flaw on a scale larger than the individual.
The simple definition of normative behavior does not fit into what I am trying to explore, nor do I believe that was what the original post was trying to explore.
