I would think that any crossdresser that would want hormones would at least be transgendered ( to the minimium where they at least need to be female on some level). But I'm not expert. Perhaps there are cases of Crossdressors that use them. But usually crossdressors are just men that like to dress for whatever reason.

But whatever the case always consult a therapist and ultimately a doctor. Taking Hormones without this type of help will only lead to serious medical and emotional problems. From what I hear its not an easy transition. And if you really don't want them, they could really do a number on you emotionally. So consult with a therapist you feel comfortable with before doing anything else.
