OK I'm not sure if this has been touched upon, but I think its worth considering...
My understanding 'transgendered' persons live more in the grey area - some surgery, no surgery, T, no T, take T and stop after a while etc etc - a mixture if you will, choosing to live somewhere along the gender spectrum. "... many of those identifying themselves as transgendered or gender-bending or gender-blending persons are attracted to the concept of a constructed gender and see themselves and their lives as evidence of it... Eschewing any strict male-female dichotomy, transgendered persons instead reach for a wide range of mixtures of male and female restructured anatomies and manifest masculine and feminine lifestyles". Prof Milton Diamond, 2000. Transgender is the state of one's "gender identity", self-identification as woman, man, neither or both, not matching one's "assigned sex", identification by others as male, female or intersex based on physical/genetic sex.
In comparison to "transsexuals, who I believe are intersexed, have the body and genitals of one sex and the brain of the other making reconciliation of their sexual and gender identities problematic. They solve their problems of reconciling, their disparate sexual identity and gender identity, by saying, in essence, 'don't change my mind; change my body'" Prof Milton Diamond, 2000. These terms are NOT interchangeable.
If you were to say to me 'am I transsexual if I don't want a penis?' - I would say that is unlikely, nearly impossible. The better questions for you OP is were you accurate in labelling yourself 'transgendered' which my answer would be - absolutely you can still be transgendered and not want a dick. If you were meaning to refer to yourself as 'transsexual' - then no I really don't think you can. Or is it the case like others have said, were you referring to the current variations of penis modern medicine can create for us?? In which case again - I don't entirely blame you for not wanting one!
Remember absolutely no judgement here mate, I personally have always felt something missing for me and yep that's a dick (amongst other things!). I am a man, with a transsexual past and while I can appreciate not everyone is going to 'fit the definition' and I accept your right to feel the way you do - I think we, well at least I, am just trying to understand here brother!!
