Flat, puffy, inverted nipple? What to do? (Photo)

My nipple is so not aesthetically pleasing. I am an 18 year old female and I am not sexually active and never been pregnant. My right nipple has always looked like this, my left nipple is equally flat and puffy but at least it will pop out whole when stimulated or cold. My right nipple (pictured) will not come out no matter how cold it is or how much suction from a cut open syringe (google told me to try that, don't ask). I try to pull it out but it won't budge. What could I do?
