I am a man age 23. since the age of?

11 i got something like g size in my . i can open my clothes in front of people, its really embarrasing. i showed doctor in bangladesh. they gave me homeopathic and othe medic but it did not work.then i was plan for operation but my family did not give permission. they scared if any thing go wrong. i m in uk now and i spoke with doc here london. i want to do operation, though i m student so the nhs(national health service) in london could not fund for the op. is there any option to reduce the size of my without operation. its not too big but still it looks awkward,its remain the same size as it was till today.
