You need to do what is best for you, there are men that don't care what size you are and men who like smaller. don't listen to people who tell you not too just because they like big breasts! If they cause you pain or bother you badly enough to make you think you need a reduction you should follow your own head/heart
It's bad if it hurts your back and contributes to bad posture because of the strain. Speak to your doctor, surgery usually isn't covered because its considered cosmetic, but because of your size you might have a shot if he can prove it's causing health issues. Good luck!
Most guys will tell you it is a good thing, however they never had to carry that weight. They can cause neck, shoulder and back pain. Reduction surgery will help, It is a much more invasive surgery then implants, and require a longer period of recovery. If you decide on the surgery make sure you have a good surgeon. Don't be afraid to check up on him/her with the medical board. Check to see how many complaints have been filed or if he has been sued.
As long as its your choice I mean when I was younger I was disappointed but mother nature was kind to me and I'd never give it back. But some women in my family have DDDD and have back problems so if your in pain or it's too much of a hassle then think about it but doing stuff like that requires some serious thought good luck <3
