Thank you.
My son is man size, 6'3, 250. He's scheduled for this Tuesday. I've decided to change my thought process because you're right, life is full of risk. He said to me last night, Mom, even if I lost 50 pounds, had a six pack abs, I'd still have C cup boobs. So, off we go. He'll be fine, he'll be free. I was more concerned about his adult sex life, I didn't want him to feel intimidated or ashamed later in life. I want him to enjoy all that life has to offer.
Will let you know, we are excited:)

Your a really cool mum, 14 is pretty young to get the surgery but it does sound like puberty's hit him pretty rapidly. I remember being 14 looking in the mirror and thinking why isnt my body like the rest of my mates, its great that hes going to be address it so young.
Your worries while all rational, are not of any concern

. If you go to a good surgeon, he will get a good result. Risk of infection is tiny any half decent hospital will protect him against this. The surgery isnt actually that bad at all, although its invasive surgery its a day case, he will be booked in the morning wheel'd in some point in the mid morning/afternoon and will be leaving the hospital that same day. I went in for surgery at 11am and left at 5:30pm. It was a similar experience to having a tooth out.
But recovery (may) be an issue, and since he'l have you helping out it will be slightly easier. Dont mention this to him yet, just be prepared if he does experience this.
Recovery is more of a mental process which may take some time to adjust to, especially due to his age. Once he has the surgery, he will feel great but then he may experience scar tissue/swelling a few weeks down the line. Most people find having the initial euphoria of having their gyne fixed, to having a misshapen chest heartbreaking. Depending on the person it can be a drawn out process, and lots of people seriously underestimate the mental anguish the surgery can invoke. But it does get better, and in the end he will be so relieved when its all over.
Im not saying to to scare you, its just good to be aware of the pitfalls in recovery if you look through the forums you will see it mentioned a lot. Dont have ANY reservations about the surgery, your doing the right think and your son will thank you for being so supportive.
