"Hi all, This is my first post so be nice please

Having had an Orchie back in 2010 after 3 years taking hormones I felt I could comment on it's effects. An Orchie isn't a substitute for SRS all it will allow is a smaller dose of Estrogen due to there being less Testosterone, The physical appearance of the male parts are altered slightly and as people have said erections and orgasm are still similar to what was possible before although what comes out isn't anything like it was".
Hi Sorcha,
I'm new here as well, so you're in good company. :-)
Of course, each person has varying experiences along their transitional journey. In many instances an Orchiectomy is performed for girls in transition instead of SRS. After it's completed & the body gradually begins to adjust to the massive drop in T levels, a sense of liberation surfaces. I had been on a healthy dose of Spironolactone just under two decades & the whole time my T levels were just as high as my estrogen levels, conflicting with each other which was very frustrating. I had been strongly advised by my endocrinologist (that the only way to successfully counteract the testosterone was) to have an Orchiectomy. Finally had it done last year & not only have my T levels dropped to below that of a genetic female, but the estrogen effects became more apparent. More pronounced.
While it is certainly true as you say, estrogen doses can be lowered, not having to ever take T blockers again or even a reduced dosage is less taxing on the liver, kidneys & there is no further need to worry about blocking testosterone by taking said blockers. If one goes off them for medical or financial reasons, there is no worry of a resurface of T to undo an orchiectomy's effects. So, while blockers have their use, & can lower levels as long as one continues their regimen, castration is a good notch above that ensures no reversal of masculinization if one had to cease medication for whatever reason, & there's less bulk than if one were on blockers, even with the shrinkage from taking them for years.
I have found at least in my case, features have gotten softer & my shape is slightly rounder as opposed to before. Also, one is endocrinologically the same as a transwoman whose undergone complete SRS. I can also attest that my libido is alot lower than it was before & the orgasm is clear. I've heard this to be true of other girls who have had the procedure done as well. It's as I said, everyone's experience varies on this journey, but it's good to share thoughts on these issues & hopefully be an inspiration or somewhat of a reference guide to others on our experiences, thoughts & opinions. :-)
