hey, i would be willing to answer some of your questions.
1- Intersex can be a very vague terminology from what I've gathered, it can include CAIS, PAIS, Swyer's and others. If your going to refer to someone as a hermaphrodite i think its important to know where that person stand on the spectrum of DSD's are they made up of male and female parts?, there are people with CAIS who dont have any secondary sex differences, and there DNA is just different so to call them a hermaphrodite( atleast to call me a hermaphrodite, may be extremely insulting) I'd much rather be refered to as someone with CAIS.
2- Im not really sure about what to say about the surgeries. In my class we studied the Brenda/Bruce Rhiemer case( if thats at all helpful, its basically about whether gender is nature vs. nurture)
