No offense but I am not concerned with what guys prefer as far as scarring.
None taken, just was not sure how you balance your self image, so in an absence of defined boundaries, I filled out the corner cases.
>> I also don't have pale skin, I am quite brown.
In general, scarring is less initially color shifted on darker skin, although if memory serves it tends to stick darker with time. Since I was not aware of your skin tone, I offered my personal experience. Taking the red or purple out of pale skin is harder than with darker skin as the lack of pigmentation cannot hide it. So, you might give bio oil a try or do some other research focused on your skin tone. Or ignore the information as not applicable to you, as you choose. You have some other cosmetic options, fractional lasering is one such:

The actual site owner admin here has a gf who is Asiatic, and I believe a bit of skin toning. You might try sending a private message to Kwukduck and see if he has more direct input.
>> Usually when I see adult personalities with larger scars in the fold, they are noticeable.
It is possible since adult stars are marketing to a fan base that may prefer scarring, or simply not care, that they chose to do nothing about it. I would not necessarily use that as a frame of reference for what normal scarring would be. It would be ideal tho, to check on people who share your skin tone.
>> I already have scars and lost some sensation around my breast (luckily nipples are fine). I am wondering if I would lose more sensation and potentially in a different location and end up with a larger area of sensation loss.
As stated above, ALL surgical procedures that sever nerve links through the skin run a risk of incomplete, or non existent return of sensation. Statistically this is about 10-20% of cases. Each time you undergo the knife, you roll the dice. This risk factor does not change substantially by incision location unless you have a bad nipple incision doctor.
But what can affect it additionally you did not acknowledge; compression from the bra afterwards. This can also exacerbate nerve elongation, which is more common to result in numbness and partial sensitivity loss than outright cutting, since it is less of a pathway-rebuilding exercise for your body, and more of an atrophy situation. This can also couple with restricting blood flow, which can also negatively impact nerve regrowth during the healing process.
Sorry I could not be of more help.
