Why the hell are my boobs so big?

I m literally only 15 and I hate them. They re a 34G. obviously by the 34 u can tell I m not really fat or anything but not skinny. I m average and my boobs are too big for my body. Everywhere I go older men always try and talk to me and bras are so hard to find in my size and all the other girls have cute small perky boobs and I feel like guys my age only joke about my boobs. I hate them so much. Should I get a reduction. They don t ever hurt but I just am sad bc guys only like women with small boobs and big butts and I have like long legs and don t have the hippy/butt look. What do I do. Any other women who have boobs that went thru this? My mom didn't even get huge boobs till after she had me.
