Strictly speaking, Intersex refers to variations of sex characteristics, so including things like soft skin and other non reproductive structures may not fit the scientific description. We are all different, mesomorphic males have a body shape and fat compositions more associated with women, but they aren't intersex. I expect that there will be a redefining of intersex at some time in the future, but currently, it is still about reproductive characteristics.
A doctor suggested I might be intersex due to some developmental variations, but these were attributed to hypogonadism. My T was low, so I never need an anti androgen, but, despite some difficulty, I was able to reproduce. Some intersex people can reproduce, but very few. I am transgender. To me, this means that my brain developed differently and is not congruent with my biological makeup. That my brain developed more like a female brain could one day bring me within the description of intersex, it doesn't atm. I am OK with that, as it makes no difference to how I have lived, or will in the future.
