That's interesting, and I totally believe it. Knee replacement recovery is much longer than the 2-3 weeks they claim for mtf srs. And some people end up with further problems that require more surgery to fix. And artificial knee joints only last a decade max and need to be replaced. But it's also very different because no one cares about their knee except that it works without pain. I wonder the amount of complications that a srs patient would ensure and still be happy because of the psychological improvements. And of course those psychological improvements are very real and matter. I do have a hard time understanding that and maybe that's just because I'm older and my genitalia really doesn't matter to me as much as it once did. Like there's plenty else about myself that I'd like to change, like my weight, painful joins, weak muscles, saggy skin, age spots, etc, before I'd worry about the shape of my genitalia. But I understand that everyone has different perspectives and I'm ok with that.
