I want to get silicone implants, since they feel more natural and less like water balloons. I'm 18 and I don't plan on going any bigger than maybe a C. I'm 6'3", thin (but I have some breast tissue), and my chest is relatively small, if I do say so myself. I've read that I need to be 22 for silicone implants. Well, I'm graduated and I'm essentially an adult now that I work full time... so can I get silicone implants?
