Gynomom,
First, I commend you on taking control of the situation of dealing with your son having breasts at such a young age. In early teen years, there are so many esteem issues that need to be dealt with. This situation creates an incredibly unique challenge that no one is prepared to handle. I feel that you are on the right track of educating yourself, asking for help and opening the lines of communication.
My situation sounds similar to your sons. At about 10-11 years old, I started to develop breasts. I was chubby as well, but there was no conversation about it. Not from my parents, siblings, doctor, nobody. When I got to 7th and 8th grade, I few guys and a lot of girls told me that I was big enough to wear a bra. I could also see that my breasts were bigger than 70% of the girls in the 8th grade. A little embarrassing, but I just kept it inside and deal that wit her it. I played sports in school and gym classes weren’t a problem. I had a great gym teacher who always made sure that I was a shirt and never a skin.
High school wasn’t a big problem for me, outside of a few comments. I was never touched or groped by anyone. It’s hard to tell how big I was, probably a solid B cup for sure.
I’ll fast forward to about a year ago when I stumbled upon this website and really started to seriously investigate to idea of wearing a bra. In December 2019, I sat my wife and 2 sons( ages 21 and 18 )down to explain that I would feel more comfortable wearing a bra full time. They were very supportive and told me that they loved me and do whatever I needed to do to be comfortable. So I got fitted and have worn a bra daily since the middle of December. I’m 50 years old and not interested in surgery. Probably something I would have benefited from a long time ago. While it would have been a bit embarrassing, I probably would have been more comfortable.
My 18 year has gynecomastia too. He’s in the A/B range. He’s a bit bothered by it, but doesn’t let it bother him. I told him whatever way he chooses to deal with is ok as long as he loves himself.
I’m here to lend an ear or give advice, whichever you need. Good luck to you and your son as both of you navigate your way to acceptance.
