Nowadays, GRS is basically expected in a transition.

Not in grown males, it's not. The vast majority of TIMs have not had, nor do they ever plan to have, genital surgeries. When "gender confirmation surgeries" are spoken of for TIMs nowadays it almost always means facial feminization surgeries; tracheal shaves; having sacs of fluid or gel implanted in the chest to resemble women's breasts; lip, butt and hip injections with fillers; dental contouring, etc.

The trans research org the Williams Institute reported in 2015 that the vast majority of males who claim to be trans - 88% - have not had any genital surgeries. Since then, the number of trans-identified people has skyrocketed. But there has been no corresponding uptick in genital surgeries on males. So probably 95% or so of TIMs have their genitals intact.

The most common "gender confirming surgery" being done today by far is double mastectomy on young females. Yes, many males who claim to be trans are having surgeries - just not on their genitals. Instead, they're rebranding their male genitals as female genitals - lady dicks and so on.

Even prominent trans people who in the past claimed, intimated or pretended they had gotten genital surgeries - such as Blaire White, Gigi Gorgeous and C Jenner - have more recently admitted that in fact they did not. Jenner now says he didn't have his male genitals removed, he just "retired" them.

Once males have been through puberty and discovered the pleasure that male libido and male genitalia bring them, the vast majority are understandably very reluctant to part with their dicks and balls. That's one of the reasons why there's such a push in "trans medicine" to get kids to identify as trans and to put them on puberty blockers when still very young. The surgeons know that a boy or man who has never been through puberty and never experienced libido, sexual attraction or an orgasm like Jazz Jennings is much more likely to go ahead with genital surgeries coz he won't have an understanding of what he's losing and missing.
