NOTE: I have provided numbers for trans women, buy I do not have numbers on trans men or trans nonbinary folks. There is likely to be deviation in those groups from the data I have provided.
Estimates from the US provide that only as much as 50% of trans women want to get any type of gender-affirming surgery, let alone bottom surgery, which is the hardest to recover from, the most difficult to get, and generally among the most expensive procedures available. Current estimates also provide that about of 11% of trans women in the US will be able to get bottom surgery in their lifetime. Keep in mind that in the US, 35% of trans women do not have health insurance, making it practically impossible for most of that 35% to even get it. Of the remaining 65%, there is still significant costs to get surgery, including not only the payments to insurance, but also travel and accommodation expenses (as you’ll need to remain near the hospital u get it done at for around 30 days post-op). Many of us will never have the means to get it, even those of us who want to, especially with how disproportionately poverty affects trans people.
Me, personally? I’m going to get it. I don’t care what else I have to give up, I will either get the surgery, or die trying. My girlfriend is the same way. But again, only ~50% of trans women even seriously want to get bottom surgery, and that’s on the larger side of the estimates.
Trans women should have agency over their bodies. We, and no one else, should have the ability to make those decisions for us. There are many trans women not interested in surgery, and that’s completely fine. Surgery doesn’t make a trans woman any more or less valid, or any more or less of a woman. Every trans woman is a woman, regardless of how they choose to transition. Some of us don’t even want to take HRT. The idea of a “full transition” is ignorant, and transmedicalist. However a trans person wants to transition is their own business, and it’s certainly not up to cis people to decide what we should do.
That being said—for the same reason of bodily autonomy that makes your description of it problematic—someone who attempts to inhibit a trans person’s ability to transition in the way they want is obviously in the wrong as well. It is no one’s choice but our own how we transition.
If you ever have a question about what a specific flag does for a command, type
man [insert command here]and RTFM (respectfully, of course). If you need a shorthand that’s less verbose, most commands have a--helpor-hflag that prints out a quick overview of how to use the command and what the flags do.
