Nose Not Masculine Enough

If you are otherwise happy with your nose and would prefer to avoid surgery, I would leave it alone. That being said, the first thing I note about your nose in profile view is that you have a very low nasion (junction of the forehead and nasal dorsum) in the setting of a more prominent forehead.  If you were to opt to have a revision, my suggestion would be to increase the height of your nasal dorsum (with cartilage grafts), which appears somewhat scooped out. 

While there are certainly a wide range of normal features in male noses, having a strong nasal bridge is a common one. A good way to think about this is to see where the nose starts (up toward the brow, between the eyes). From your photo it appears that your nasal starting point is relatively low. Ideally the starting point is closer to the upper eyelid lash line. Your nasolabial angle seems within normal range. It appears off balance due to the underprojected bridge.

Improving the projection of the bridge with a graft would effect a more natural and masculine appearance. It would also tend to make the bridge appear less wide on frontal view and also help make the eyes appear less far apart. Grafting is usually done with cartilage, although some surgeons use implants instead.

Without being too critical, it appears that your nose lacks sufficient projection along the entire profile, giving you a scooped look that as a result makes the tip - which is somewhat bulbous- appear upwardly turned. To correct this is a rather complex surgery, but you can find an experienced surgeon who can in fact make a huge improvement.

From the pictures, it appears to me that your bridge is somewhat underprojected.  A "strong" bridge is a masculine feature for the nose.   The starting point of your nose is very low, which makes it appear somewhat short.  Ideally, it should appear to start at the level of the upper eyelashes or the upper eyelid crease.  The nasolabial angle, in my opinion, seems OK.    All these observations, of course, are made without being able to compare to your preoperative photos. 

Rather than calling a nose masculine or feminine, it is more accurate to describe whether or not it is proportional to the surrounding facial features, regardless of gender. I feel your nose would be improved by augmenting your bridge and radix. Your nasolabial angle is within the normal range.
