I have manboobs?

I Know i cant get rid of them without surgery.
I was 278 at the start of june i am now 256
If i lose say around 30 pounds will i notice a difference?
I no i can lose 30 pounds by september.
I also work out 6 days a week. Will chest exercises make my chest more defined or just make my **** stick out more?
If i do pushups how far should i arms be to work out my chest? plzzzzzz im also 16 and i dont shave, i have moderate underarm hair. Could this just be a hormonal problem
or full on gynecomastia. 17 in january

You may have a combination of obesity and gynecomastia. Hard to tell. Weight loss is what you really need right now, and it sounds like you realize it and are doing something about it. Get down to your fighting weight and then see what you are like, in some rare cases breast reduction is required on a male. But I said rare.
