This is the first time I have read this, and I can say I can relate to this...a lot. A brief story of mines so you get an understanding of my relation to this: I was always the kid that used to eat so fucking much. Eventually it got out of control and I was about 260 pounds 5'5 in the 6th grade. Back in 2010 I got all the way from 255 to 190 in 6 months. I was looking my best, the best in my whole life. I was lucky I didn't have loose skin, but the stretch marks stayed. Mostly on my right shoulder, and I see you don't have stretch marks (lucky). I managed to do the 180 but then I started meeting girls and bullshit happens partying smoking drinking and I'm at 5'10 220 now. I'm not gonna lie, the girls get to you.
I feel how you feel with your body. You already reached all the way here and nothing is perfect for you. Honestly, your man boobs aren't even noticeable. It's just a thing in the mind where you have already achieved something you thought impossible, and you're still hungry for more.
As for the bulking part, I would suggest it's up to you. It really depends on what you want to do you with looks. Bulking is a great idea...but you will lose a lot of your already accomplished goals. Your v will be gone and so will your abs. You will not gain much fat you when you look at yourself in the mirror you will see that "big" figure again. Take in mind your eating habits, if you have succeeded in suppressing them, will come back with a bulk. And if you love food like me, it's gonna be a bitch knowing your doing something to help yourself but you can easily over-do it. Bulking can become like a drug. You will pretty much be looking for the right way to do the wrong things. Don't get me wrong, bulking is not bad at all. It's just that, in my experience, bulking has sometimes gone overboard. If you're not disciplined enough to handle yourself, you can go overboard easily.
IMO, i'd say stick to your diet for a little bit longer. Don't make it a diet; make it a lifestyle. If it matters anything to you, you have so much respect for me. Congratulations.
