Hiee,
I have musing about this for some time now, well actually since my Orchie back in May of this year.
My musings are mostly concerned with M->F's but would apply to F-M's to some degree although differing proceedures are indicated.
Back in the days (GRS)/SRS was commonly called a Sex change operation, primarily because and orchiectomy was bundled with the vaginioplasty. Today that is NO longer the case as Orchie's can be had on their own account much more readily then in the past.
The issue being, either an orchiectomy or hystorectomy is actually the operation that changes ones hormonal system by eliminating the organs that actually produce the birthsex Hormone in any quantities.
I consider myself to be Post-Op albeit a Vaginioplasty Pre-Op which in my case is only a cosmetic surgory anyhow although one that will allow my mind to be much more at peace.
OOOHHHHH aren't Labels sooooooooo much FUN

Comments anyone?
Byee,
Brina
