i had butt implant 3 years ago but from day 1 i knew that the implant were to small. It is a good job in the sens that they don't move but i am not satisfied as I am using pad to make it bigger. now I noticed that they look flatter than a year ago and I am worried if they are getting flat. In addition I have no curve and I wanted some curve which is very important for an african american women. Is it possible to get bigger implants? Have fat transfer to have hips. I am actually 150 pound small.
