Believe me I can totally relate! I wear a 50DD and the cup is a little small but it flattens the breast some. My VA doc said I should go for a fitting to get some bras that fit better so I can wear them all day.
My wife and daughters told me for years to wear them, most of the rest of my family knows that I do and support it, and admit their boobs are not that small but not near the size of mine, but mine are so huge because of the total loss of testosterone.
I've had many surgeries and as a diabetic I stick needles in myself 6 times a day or more, so trust me when I say that you could get through a surgery, but some surgeries are required some are not and breast reduction is not a required surgery!
Yes, people are very cruel! I try not to bring attention to myself by wearing a button down shirt even left open over a t-shirt that is a size to big. This will hid the size of your breast some, and if someone has the "balls" to say something you need to come back with a counter, like "so you get off on men with breast, I prefer women myself", if it is a woman "does your husband know this about you, maybe he should get his balls crushed in an accident and his will grow too"! The last, getting your balls crushed will work with a guy as well, and they will feel like an ass.
Dr. Jacobs and I started a letter writing campaign a while back to try a get Dr. Oz to do a show about gynecomastia to help bring more awareness about it to the public and also try to get more insurance coverage, but we never heard from Dr. Oz.
We are all here for the same reasons, some for surgery others for acceptance, but to support one another!
