Like some of us here on the forum I have been dealing with breast growth for a few years, however, in all the dealings I have had to deal with (friends finding out, co-workers finding out, bosses finding out, fellow students finding out and more) I never informed my mom (she is 97 and still sharp as a tack, drives with no problems and we had a discussion 3 weeks ago on astrophysics...she held her own). Whenever we would get together for any event, I would make sure I suppressed my breasts as much as possible so as not to show anything. I would wear breast pocketed shirts to aid in hiding my assets. Last Friday I finally told her and she took it as no big deal. I always expected her to throw a tizzy or freak out in some fashion...she did not. She showed great concern and is willing to aid me in any way she can. When I told her I was suppressing my boobs due to work but today I wore the most comfortable bra I could and a tight tee-shirt. It hid nothing (46 C/D mostly D) and while comfortable was most revealing. She thought I looked good and had a nice figure with the breasts. Go figure.
The point of all of this is: regardless of our personal fears, going through anything that can possibly cause our death is simply not logical when having breasts, and 46D is nothing to ignore like so many of the smaller cup sized brothers, can be a simple irritation to overcome. People, particularly family, love us and care for us. Co-workers and bosses are not out to make an issue of our breasts to humiliate us. As another example, I am at work at this moment (my office on my day off) and supervisors have popped on by as well as numerous co-workers and I am just slightly suppressing my boobs but they are unmistakable and no one has said or done a thing relative to them. Accept the boobs! They are a part of you and be comfortable with them. Remember, things could be a lot worse...it could be snowing! As one of the other more distinguished and well endowed gentlemen has suggested: if you are feeling a bit low because of your boobs, go buy them a nice bra and you will feel better. (by the way, this advice works)
Hopefully I have added a bit of good advice to the discussion, otherwise...oops!
