@ikea_femme I had erections at one year, it never really went down. The things that I lost were _unwanted_ erections.
Right before bottom surgery, basically the only time I liked anything about my genitals was when I was using them to penetrate partners. Whether you'd regret depends on you more than it depends on how you like your parts now. Unfortunately I don't think anyone can answer it - you can't really know until you do it.
