Damn, they don't seem like monozygotic twins. If they were it would beg the question of "if trans is a natural occurrence that has biological substance, why didn't the other twin sister troon out?"
Since you're reading this Elephant Dick, let me tell you something: I'm guessing that you may have not felt like a woman because you've been compared to your feminine twin sister multiple times by your family or your internal dialogue. That doesn't make you less of a woman, and that doesn't make you a man.
It may seem like you have to keep going with transitioning because that's what you're supposed to do as a transman but you can just stop. You're at a crossroad: continue with the surgeries, spend thousands of dollars, and worry about dehiscences and rotting flesh, or stop all together and walk away. You don't have to endure all of these complications, and the surgeries sure won't fix your problems. Even when you surgically fix the lack of a penis or existence of breasts you're always going to find something else that's faulty about your body. And you'll hyperfocus on it until it becomes unbearable and you feel like you need to surgically fix it.
The only way to break the cycle is to love and accept the body that you have. Love yourself Elephant Dick. Except the misaligned tube of flesh on your stomach. Cut it off before it get infected.
The photos make it obvious why she trooned out. To add onto what you've said, the vast majority of people have image problems, especially with siblings. 99% of people are not where they want to be. No one has the perfect job, the amazing salary, the infectious smile, the whitest teeth, the sexiest pair of tits, the longest cock, the most prestigious car, the most likeable personality, the largest friend group, etc. We are all lucky in life if we reach perfection in one area, doubly so if it is something we are born with and not something we had to put effort into.
Something I came to terms with very early on was that, no matter what, my body is mine. There are none out there like it. I have surgical scars, I have a spine ruined by carrying 100+kg glass panels, my brain cannot comprehend anything above basic maths, I have a family history of arthritis, but this will never hurt me unless I allow it to. There is exactly zero point in fretting over it. All it does is make life even more stressful, make finding someone who will accept you even more difficult because of how shy about it you are, and make you depressed when you don't have to be. There are always things we have to accept and live with. Even those with actual gender dysphoria are better served by accepting their place and trying their best to live life as the gender they do not view themselves as. You will find it far easier in life to do so. And, hopefully, you eventually come to peace with it and the dysphoria will disappear.
Something which should illustrate how warped your perspective on being a man is your fake penis: most men are not happy with theirs. Most who are happy are either those with ones that look like something from a porno or spent years, sometimes decades, until they finally got over it. Most don't. Probably close to 70% of men are unhappy with theirs, even for very minor things, or stupid things like it only being six instead of seven inches. Anyone with something that looked like yours would be in the bottom 25%, those who think about it everyday, go online and spend thousands of dollars for quack therapies to fix what problems they think they have, etc. The fact that you are supposedly happy with it today despite it clearly being a botch job with much more progress to go before it even looks like more than a mound of flesh should indicate that you are not in any way having something that even approximates the experience of a man.
Being resentful over how much better your sister looks and how much more attention she receives is fine (so long as you don't take it out on her personally). It's another thing entirely to somehow turn this into you being a man. The most common response for men in your position is to improve themselves through fitness, skills, etc. That's the path you should have taken, and indeed still can. It's never too late to turn your life around.
