Is there a procedure that can round out my butt more without adding to it? Not interested in a BBL, just some contouring

Well, a lot of it depends upon what you consider to be “rounder”? If you mean more projection on the side-profile view then the only way would be to place a precisely form fitted buttock implant such as a Staton Anatomic gluteal implant. If you mean more of a lean and/or defined shape then sculpting  areas around the perimeter of your buttock with liposuction may be your best option.  Glad to help  

Hello, thank you for the question.
Liposuction can help to contouring your buttocks. Make sure to visit a board-certified plastic surgeon to analyze the best options for you.
Best of lucks.

Dear Ayishag,
it is hard to tell for sure without an examination. Based on your photos, it looks like you would benefit from liposuction.  If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

Yes.  Liposuction above and to the sides of your buttocks will make your buttock definition much better and rounder.  It will not increase the size of your buttocks, but reshape it.

I agree that adding volume to your buttocks is probably not needed. I think your best option is liposuction of your love handles and improving the transition from your waist to your buttocks.
I suggest having several in person consultations where you can discuss what you’re trying to achieve and what can be accomplished in greater detail.
Best,
