I like how this Canadian guide on FTM surgery includes mention of non-transsexuals who may want surgery:
We use “FTM” as shorthand for a spectrum that includes not just transsexuals, but anyone who was assigned female at birth and who identifies as male, masculine, or a man some or all of the time. Some non-transsexuals in the FTM spectrum (androgynous people, butches, drag kings, bi-gender and multi-gender people, etc.) may also want some of the surgeries described above, and may not identify or live as men. For this reason we use the term FTM instead of “trans men”.
...
For FTMs, the goals of SRS are to reduce “female” characteristics and make the body look more “masculine” or androgynous (depending on how you identify).
This youtube video by videokidsam also has some good info on top surgery vs reduction.
