Quite true, doc. It's too bad that more sons don't feel comfortable telling their parents about the misery gynecomastia has caused (or IS causing). I think a lot of guys just don't think their parents will understand or it's just too embarrassing for them to discuss. But your parents love you like no one else does.
What sons should think about in a situation like this is that nobody is going to "feel your pain" quite like your parents will. If you explain the situation in a calm and rational manner, tell them how you feel about it, share your education with them on the subject (they probably don't know as much about it as you do), and then SHOW them your chest and the reason it's making you miserable, then they are sure to understand and know immediately where you're coming from. No parent can stand seeing their child suffer. Also, parents can easily imagine themselves in your position. Contrary to what it may seem, it hasn't been that long ago since your parents were your age. Dads can easily imagine what it would be like to go through life embarrassed to even take off your shirt. Parents know the heartache that goes with being made fun of at school. Everyone has experienced it and we can all relate to the misery it causes to be embarrassed in front of your peers.
When parents can adequately understand the situation and obviously see how much pain and misery it's causing, more often than not, they will be on board with getting the situation corrected as soon as possible. It's rare that any parent is going to shrug their shoulders and not try to do something/anything to help their child. They will do whatever they need to do to help you.
Put yourself in their position. If they came to you, upset and wanting/needing help, you know you'd do anything you could to help them. That's what families do.
