You can absolutely CD and not be TG. I love dressing up in women's clothing, but I do not have any desire to be a woman. I love being a man, and wouldn't change that, but I also love dressing up.
TS = "desire" to be a woman
TG = umbrella term used to lump us all together
The crossdressing community is one that needs to stick together and continue to be there for each other for whatever one needs. We are always trying to improve the forum to better serve the crossdresser in all of us.
