nipple size

r
ok so i'm 15 and i feel like my nipples are huge. idk if it's like a hereditary thing but i measured the radius of one of my nipples and it's about 1.5 in/4 cm long. is that abnormal? also my boobs are like really veiny idk if that's just like my skin type of something but you can see like blue veins. any comments/advice?
