boob size

So... I am going to be 16 in 2 weeks and my bra size is a 34I (US, 34GG EU). I've read online that guys (I'm straight, but for gay/bi people, girls too) are grossed out/turned off by really big boobs. Anything bigger than a handful is too much I guess. Hoping that isn't true because I really want someone to like me. Does anyone have experience or support on this topic, positive or negative???
