Hey /r/Fitness, is there any hope for me?

So I'm 20, and just recently started dating this girl with whom I've been very good friends. Since we already know each other well, and her libido is on overdrive to say the least, we're moving quick. I have gained about 20-30 pounds since I started university two years ago, but my main issue is what I believe is gynecomastia. Have a look here:

The pictures definitely don't do it justice, but you get the idea. I'm basically a blossoming preteen girl in my eyes, and I'm very self conscious about my bitchtits. I'm planning on hitting the Insanity workout on the 10th once my exams are over to try and shed some of this excess flubber but my question is, how bad is my case of gynecomastia? How prominent and full figured will my bust be if I lose, say 20 pounds? I'm hoping there's atleast a couple experts on here. These tits have kept me from taking off my shirt in public since I hit puberty and has been causing severe grief and anxiety. Now with a girlfriend I'm fearing sex and all that good stuff like never before. Any insight would be appreciated.

TL;DR: I think I have mantits and I want an honest opinion of how bad they are?

EDIT: I know, I know. I'm one hairyyy beast =\

EDIT 2: Thank you everyone for your enormously helpful (and sweet!) thoughts and suggestions. I don't know why but I guess because we all scrutinize ourselves the hardest I saw myself in a worse light than you've all cast me in. For that I am truly grateful :) I guess the answer now is obvious, work the fcuk out and fcuk her lights out =D I will definitely keep myself around r/Fitness and update my progress... AFTER my finals

EDIT 3: Never thought I'd be so relieved to be called fat!
