Hi Francis,
since you speak about your age, mine has just recently turned to 65!
That can sound ancient, though I am sure not, and neither sound you.
Having had no x's is a bit unusual, bachelor(es) may have an impact on relationship expectations. This just quickly off the top of my head.
Now to orchie.
Myself I looked into orchie, after my craniotomy (due to subdural-haematoma, knock on the head) because of monetary concerns first and foremost. Scraping the bottom of the barrel I decided SRS is still on, following I will see what comes next. Hopefully not 6' under as yet. Eh, no please!
I guess you have no shrink's SRS "referral letter", you don't say, and so now look into orchie.
At 59, T is far less an issue as is for the younger girls as it quite normally drops off for many, by quite a lot, as was the case for me.
It had no impact on my libido, but it had for maintaining an erection in hetero sex, trans issues also come into it of course.
I don't know where you stand (pun intended) with that?
You will not for some time be using ANY LESS hormones after orchie as your body via adrenal glands will try compensate for what ever T loss it will "see".
In fact my T has become VERY low 0.7 nmol/l, the normal MALE rage = 8.0 - 18.7 !! at age ~ 60.
I still took Spiro AND Finasteride for some time but have stopped now, and I am feeling the better for it.
So, again... why bother with orchie?
For me there also is an emotional issue. The idea of being "de-balled" does not appeal. It seems a curious semi-step on a girls journey, also you could add the $$$ to your SRS savings. Decent SRS in Thailand is to be had for about $7.0k add flight food, and sundry.
Now, if you ask me, and using what you have shared, I have doubts about going for orchie.
On top of it, and I assume you are as fit as myself... WE DO NOT GET YOUNGER, how long to push out SRS if that is what you still plan for?
I would try make a plan now for SRS and NOT loose much more time. I feel you may very well just get stuck after orchie and not bother to complete there after. That would be a shame... I feel.
There you have it, those are my thoughts.
Think hard,
Axelle
