What Can Be Done to Improve the Appearance of my Nose?

Although it is difficult to tell from the single posted picture, rhinoplasties can be performed without feminizing a nose.  By removing the dorsal hump through a series of maneuvers to refine it, this will typically not feminize the nose.  Judging by your picture, minimal to no top work would be advisable.

Male rhinoplasty should be addressed differently than rhinoplasty in a female.  The aesthetically pleasing proportions and measurements in a female nose are different than those of the male.  This is always taken into consideration when performing male rhinoplasty and should be addressed by your surgeon prior to the procedure.  Keeping a strong profile and avoiding overrotation of the tip are essential aspects amongst many when performing male rhinoplasty. 

Yes, this is what good surgeons do. Look at the work of experienced rhinoplasty surgeons to find one that does refinement of male noses without feminizing them. Your bump can be removed without a "scooped" look and the tip made less bulbous without being "pinched".
