Dude, i dont want to be an ass or anything, but the amount of gyno u have probably shows even when ur laying down. U should really get that checked. It's a simple surgery and it can get fixed really fast, by judging the rest of your physique its safe to say u dont have a high BF, which means its breast tissue, it wont go away naturally. No mean to disrespect u or anything man. just giving some advice.
It is not really bad compared to other extreme cases, but seeing that u train to improve your body, removing it would make your overall physique look better IMO. Just check out the options and consider it man, its not gonna improve your perfomance, but it will enhance your look and make you look more like the athlete you can look like.
