I'm in agreement with no wanting to id as a transman or FTM. In fact, other than Susan's i don't function in the queer or trans community. I do my piece in these communities by agreeing to do speaking engagements. I'm usually asked to share my experiences regarding living as a heterosexual man and wanting to function in the mainstream community. As most guys, who are transitioning or have transitioned there are unique experiences in learning how to live in mainstream society, which are some what different than those guys living in the GLBT community.
I live as a man 24/7 and have completed my R.L.E. and waiting to secure a date for lower surgery. All my personal identification-including my birth certificate now indicates I'm male. Something about changing that gender marker legally adds to my identity as a man - not a transman. Does the personal identification change my transsexuality, no, it doesn't. That said, i will only have that conversation with those individuals that i choose to share that status with, due to the intimacy of our relationship etc.
Cheers,
Guy
