Is it possible to shrink my ribcage?

hey girl, what are you talking about, what are you dating a 12 yo boy? what the hell is that? this is completely unfair, listen, a guy that makes you feel unpretty is not worth your time or you thinking, if he doesn't "love" and lust for the way you look (not only if he is okay with it or not) then get rid of him immediately, you should have known that from the start, one doesn't need stress about the way they look and you need someone that appreciated you. When you grow up more you'll have a bigger breasts because of your body form and that's very sexy, you sound like a good girl and you know what love is, but the jerk you're dating isn't anything like you, he is too much into porn models probably or lame models (the sick body standards) like barbie dolls or very skinny disgusting ones, those are of no use for anything, not even sex, just to feed the hunger of those guys with twisted taste in women to stare at their bones covered with "burned" skin.

say to him this is the way I am, you don't like it then go away. and there is nothing about gaining weight when you grow up, all women experience that and if it was moderate then it can make a woman more feminine and attractive for her age... and if he has set it clear and said to you we'll divorce when you gain more weight then why would you take the risk and get attached to him? you wanna suffer and deal with cheating and break up after couple of years?

if he doesn't like you how you are then he doesn't deserve you simple as that...

Just because your boyfriend says he likes smaller girls doesn't mean you should change your body type for him. There is no proper way to shrink your ribcage. It's dangerous to even think of such a thing. You are your own person, and if your boyfriend can't accept that, then he should find someone else.

Your bones actually respond to stress; they have osteoblasts (which add calcium to the bones), and osteoclasts (which take calcium away from bones). Through those two different kinds of cells your body is able to reshape your bones over time. You have muscles running up and down your ribs called external intercostals and internal intercostals that pull the rib cage in and out when you forcefully inhale/exhale, and it's a known fact that when people have breathing problems for long periods they get "barrel-chested" because of those muscles pulling the ribs out when they forcefully inhale. If you can get barrel-chested by using your external intercostals to forcefully inhale, then maybe you can shrink your ribcage by using your internal intercostals to forcefully enhale? ...you can try it, but it would take a while.

No, but you can dump your boyfriend and get a better one. [=

You never should change yourself for somebody like that guy. What if you get smaller and petite and he likes that for a while than says you need a boob job because ..., you need a smaller nose or bigger eyes... What will you do? Run to the surgeon? You don't need to fit his standards, be happy with yourself and find a guy who will appreciate you for who you are.

He should love you for the way you are. How long yall been together?

no

you can have ribs removed, but you can't shrink your bones. why would you think about something so drastic just so that your boyfriend thinks you're more beautiful. just stop gaining weight, there's nothing else you can do. you shouldn't even have to worry about whether you'll get too fat for his taste, because if you do, then he's a piece of crap.

No, it is physically impossible to shrink your rib cage, sorry.
