Can I just say something as a guy? Hopefully it won't be automatically assumed I'm a perv since I'm in this thread. Yes, I like breasts, but I find the idea of fapping to girls legitimately cosplaying (even for attention) to be odd.
Anyway, I just want to say that I, for one, don't care about breast size all that much. I think a woman that looks like all her parts fit together is the most attractive thing. This isn't meant to discourage you from a reduction, by any means, but just letting women know that not all guys care about breast size. And in the end (for me at least) you could have the body of a goddess, but if you have a horrible personality then you aren't really attractive to me in the end. Eye candy without substance if you will.
The little bit I've gleamed about you from your posts make you seem like a nice and sensible girl that just wants to feel comfortable in her own skin. Do what needs to be done! Put yourself first. Don't worry what others will think. Look at Soleil Moon Frye. She got a reduction at 16 because they were causing pain.
Pretty much just saying do what you need to do to be happy. There are guys out there that won't care much about your breasts if they truly are interested in you.
tl/dr: Big boobs are nice, but being comfortable with yourself and pain free is more important.
