Misinformation like this can be incredibly damaging to those who read it. You are basing your entire post on assumptions that directly contradict reality, and all the research we have to prove it.

First off, for breast augmentation, nerve endings live largely in the dermal layer, nipples, and mammory glands, which remains untouched by augmentation. Breast implants are placed behind the breast tissue and mammory tissue, leaving everything on the surface with just as much sensation as was there before (granted, it can take time to recover from the surgery and regain sensation, and there is of course the rare risk of complications, but that is not the outcome in the vast majority of breast augmentation surgeries). Additionally, you can choose to get the implant under the muscle, even deeper than subglandular implants.

If you decide to change the location of the nipple, then yes, that comes with the risk of loss of sensation. A greater risk than is present in basic breast augmentation, but still not an expectation long-term. The only case where it is expected to lose some sensation is a free nipple graft, in which the nipple-areola complex is separated from its original nerve supply.

Then there's SRS, and I have a lot to say about that. I'll keep my thoughts condensed though, as I don't have the free time to write all of them in this comment, but I'll lay out the essential parts. For SRS that is done from someone with a penis, with the goal of creating a neovagina (or even just a neovulva), penile tissue is used to ensure erotic sensation. Good surgeons are incredible at working around nerves to ensure you have as much sensation as you realistically can. It is normal to lose sensation and gain it back over time, as the underlying structure of the nerves needs to heal from the surgery. Some people will never have the same level of sensation as before, some will have more sensation—and that's for a reason you clearly haven't considered. Genital dysphoria can significantly stunt the pleasure someone receives from sex. Having genitals that align with one's wants allows the mental roadblock put up by gender dysphoria to be taken down. This is why trans women who get vaginoplasties are generally incredibly satisfied with their results. Living in a body that does not align with you has a dramatic effect on one's ability to gain pleasure from sex. Not only that, but it completely changes they type of sex that we can have, and how sex is performed on us. That, itself, is incredibly affirming. Many trans women will stand behind their opinion that bottom surgery was (one of) the best decision(s) of their life. Besides, even those who lose sensation often agree it was more than worth it to finally feel aligned with their body. It's so much more than just about sex. And on that topic, sex is so much more that just orgasming. If you believe that's the goal of sex, then I'm sorry. The best sex I've ever had in my life didn't involve an orgasm. There's so much more emotion and intimacy that goes into sex beyond that. Bottom surgery involves every part of how we live throughout the day. For me, I always feel it. I haven't gotten bottom surgery, and it's a constant source of dread throughout my entire day. It's like this phantom feeling of something being there that shouldn't be. It feels awful. I'd do anything to get rid of that feeling and finally be able to live my life in peace and in alignment with my body. If I never had another orgasm in my life, I'd still happily do it. The same is true about any gender affirming surgery, as well. It isn't about keeping sensation—it's about feeling aligned with our bodies, and transitioning in the ways that we—and only we—decide.

It is not up to you to decide if other people should get surgery. You do not get to make that decision. The misinformation you have provided along with your gross misunderstanding of why we get surgery are incredibly disrespectful, and I find it quite offensive. The damage that a post like this can do to someone's confidence about what they chose to do in their transition is horrible. Keep those thoughts to yourself.

You are more than welcome here to talk about why surgery doesn't align with your own goals, but you have no right to decide that others shouldn't get it.
