Secondary transformation

[The First One]

What kind of changes, in addition to her muscles growing, do you like a woman in a story to undergo?  The examples I can think of are aging, de-aging, hair growing, developing a deeper voice, breast growth, breasts shrinking, clitoris growth, growing a cock or some combination of the above.  I already asked about intelligence before, but feel free to add that or anything else I missed.

I would say musk/pheromones, de-evolution (something like caveman-ese), personality shift (more aggressive/assertive), unkempt (in the sense like
more of a lived in personality).

1. Increased athleticism (strength, endurance, coordination, reaction time, proprioception).
2. Increased intelligence (memory, reason, powers of observation).
3. Increased powers of charisma (powers of personality and persuasion).
4. De-aging (rejuvenation).
5. Increased health and immunity.
6. Increased healing. 
7. Thicker wavy hair on head, longer thicker eyelashes, no body hair.
8. Increased clitoral size.
9. Improved vaginal muscle strength, endurance, and control.
10. Can be taller, but not beyond realistic impractical of height (i.e. under 6', certainly under 6'4 in an earth world).
11. Pheromones.
12. Personality shift:  more subtle and skillful, or more assertive, or more aggressive.
13. More sensitive and more selective senses (sight, smell, hearing, taste, proprioception, etc.).
