Congrats on the weight loss.
Looks like an average case of gyne to me. You're build is similar to mine, however I may have it a bit worse than you.
Definitely talk to your mom/dad about it- if you feel they'll understand and be sympathetic. It took me forever to tell anyone, but I finally told my wife, then my mom, then my dad. It's nice to not hide from them, and have someone close to me to talk to.
I also wear compression tank tops- it helps with the point and reduces the size a bit, but it's not the most comfortable thing... Also it almost looks like I have really strong chest muscles, but my arms are thin too so I still kind of slouch a bit to hide the contour.
It's a painful thing to live with man- but having support has helped me a lot. I'm seeking treatment for my hormones if needed and consulting with surgeons. My family supports me and understands how it effects my life- and that is very important for me.
Good luck.
