Time to clear the air and drop hard science on Transsexuality. The current consensus is that there are two types of Transsexual women: Early Onset (pre-puberty) and Late Onset (post-puberty), as per the DSM. Early Onset is typically androphilic whereas late onset is typically gynephilic. While the science on early onset is straightforward, as brain scans reveal they possess a structure mirroring a female brain, the science on late onset is more complicated. Theories range from autogynephilic fetishism to schizophrenic sensory processing disruption.
