I realize this is an old topic, but I wanted to update it with what wound up happening, in case any future guys want a case to reference.
I did not disclose my trans identity to my surgeon, but I did emphasize that he should get my breasts as small as he could, with small areolas. I had my consult July 31st and my surgery October 3rd. I was a 42I and he could only get me down to a 42D even after removing 7 pounds of tissue, because my breast tissue was super dense. It's been almost two months, and I've healed very well aside from two minor open wounds that were caused by steristrip irritation (and they are healing with daily application of antibiotic cream). From the talks I've had with trans guys, most of the recovery process seems very similar to that of top surgery, so top surgery recovery advice has been pretty applicable.
I was able to comfortably bind about a month out from surgery, and it's definitely easier to do so. I'm fairly overweight, so it's my hope that as I lose some weight and get on T, and the remaining breast tissue breaks down a bit from the pressure of the binder, it should get even easier to hide them. I'm definitely a lot more comfortable in my skin even with just a reduction, so I'd say it was worth it since my insurance covered most of it. If your insurance won't cover a reduction, I'd probably advise that you just save up for full top surgery.
Hope it helps someone out!
