^ I didn't quite understand what Pink Person was saying either, but although it is unconventional, I can see where the literal term "transman" could apply to both natal genders if it is understood that "transsexual transmen" are FtM and and "CDing transmen" are MtF CDers. Both are men, and both are crossing gender boundaries. (Transitioned MtF TSs also use the same word as birth females when they call themselves women.)
But, to prevent confusion, I think it's best to use two different terms altogether: transmen for FtM, and CD for CDing males (although most people do believe that CD falls within the TG umbrella).
Pink Person, I think you will continue to confuse people using the same term for both. That's not saying the community might not alter the terms down the line, but for now I think it's best to stick to the WPATH definitions, if you want people to understand who you refer to when you use the term "transman".
