Welcome to the site. I agree with you about that video.
About the girls: Confidence is key here. You've got a fighting chance if you act as if you don't notice your own gynecomastia. If you slouch, look down at yourself, touch yourself, or (horrors!) mention it
, then she'll see the gyne from that moment onward.
BUT...
If you act as if you believe you're normal (and this can take some practice), then she'll see the things that attracted her to you in the first place and not even notice the gyne. I know there's always somebody who follows one of my girl posts with something like, "Girls notice it every time and they hate it" or something like that. The people who believe that are usually inexperienced and don't know the things I know.
Basically you have a choice of staying inside and playing video games or whatever by yourself, or you can have a life. I had gyne from age 10 until I was over 40 and during that time chose to have a life. My flat-chested friends were always jealous of me because of my hot girlfriends.
I've also been told I married out of my league. I agree.
