Well I have contemplated taking estrogen hormones. That lets men grow through the same process women do during puberty, developing real breasts, and if one has alot of fat there (moobs) that would make them appear even larger. I dunno exactly how to measure mine in terms of what size I am for a guy or whatnot but I do know I'm bigger than some girls I've met before (never been with them, but know I am) I think its all genetics too where you all gain weight, and while I'm not really gaining weight too fast here, my moobs do seem to steadily growing a bit bigger every now and then. I think I could prlly get to be a D cup if i did take estrogen, but I can't afford it at this present time. And guys, I'll tell you this, it feels soooo good to have your moobs suckled! My old girlfriend did this a few times and omg its the best feeling in the world! I enjoyed it far better than a blow job thats for sure! :3 I hope my moobs never stop growing!
Pretty soon tho I'm gonna need a sports bra or something cause when I cut the grass for work they flop around pretty painfully. We should create a bra for men! The Bro.. lol
