Pectus Excavatum (hollowed chest)

Growing up I didn't have this. It wasn't until I hit puberty that I noticed that my chest was slightly caved in. My parents never said anything about it and neither do doctors. I guess I have a mild case. You can't tell unless I'm wearing a bathing suit really. As a teen I was very subconscious, but I've learned to deal with it. 
Anyway, I was wondering if anyone on here has this? I looked into it and it seems it's more common in men. 
Please feel free to share your story even if it's not you, if it's someone you know that has this.
