Do I Have Asymmetrical Gynecomastia? (photo)

Left side looks normal, right side has gynecomastia. This is not unusual. 

Surgery should improve this. Liposuction will probably be offered, and if there is firm breast tissue under the nipple and areola, some direct excision may be suggested too.

When you ready for an in person consultation, RealSelf has listings of surgeons in your area. You should consider cross referencing the listings from the The American Society of Plastic Surgeons (plasticsurgery dot org). A listing in the ASPS website assures you that your surgeon is not only board certified,  but also is a member in good standing of the major plastic surgery organization in the U. S.
Thank your for your question, best wishes.

Based only on the posted photos you appear to have unilateral slight excess of fat/breast tissue on your right side. Liposuction will improve this. Seek some in person evaluations from boarded PSs
