I listen to a podcast called Girls Gotta Eat and one of the co-hosts recently (I think in January?) had a reduction and talked about her decision making and her relationship with her breasts, how much they were part of her identity, etc. in a few episodes. Sometime last year they interviewed a friend of their who had a mastectomy and she spoke a lot about how her identity was tied to her breasts as well. Listening to those might be helpful, I can try and dig out episode numbers if you're interested.
As for your DH, hopefully he will support whatever decision you make, but I wouldn't let this influence your decision making too much. I have heard plenty of guys say they don't know why a woman would ever get a reduction, but they don't know what they're talking about. I'm in the middle of consultations for a tummy tuck and breast life and my H keeps telling me my boobs are fine, but for me it isn't as much about how they look naked but how I feel about them, how they look in clothes, and honestly I would like less underboob sweat.
If just isn’t, I am. Especially the episode where they interviewed the woman who had a mastectomy.
