Usually how long is it from when there's aching, to when buds start showing up? I'm on day 6 right now.

When do changes usually occur...as in roughly how long from when I start can I expect the following to happen?
Breast bud formation start
Breast bud fully integrates into tissue
Nipple enlargement (length and width)
Areola enlargement
Montgomery gland formation & development
Increases in nipple sensitivity

Will it be just one day there's no buds, and the next day when I wake up there's a hard lump behind one or both nipples? Is it a fairly sudden change?

Lastly, if I were to stop after breast bud formation, would I keep any of the increased sensitivity, or would it be reduced back to what it was originally?

*I already know from personal experience that if I quit prior to breast buds that sensitivity returns to normal. I'm wondering about post-buds experiences

Unless you very lucky ( or unlucky, depends on your view ), visible changes can take months, even with breast bud formation it's not like anyone will notice.

After two years on PM I was very concerned, we went on a trip to Cuba and I figured I wouldn't be taking my top off.
To my surprise, most of the older males had larger moob's than I had breast development. I took my top off, and no one even noticed. I had lost of breast bud formation at this point

Once you have breast bud formation, it's not going away. However any fat distribution will fade over time.
