I cared for my nippel sensation since Its something who is used to get me turned on pretty much..
on the other hand my cheast also the thing who have made me hide the most.
I currently have lost my nippelsensation but I got told I will get it back in some years, however it might not come fully back,
I been pretty sad about losing it even when I been used to get stimulated diffrently now, but on the other hand I feel very free to just take off my shirt and be naked with someone, and all those things, just simple everyday stuff like going out with a tshirt in the sun where hell before top surgery.

of corse its people own choice, how important sexual fellings is for people is depended on the person, for me my sexual sensations are pretty important, but I do put my everyday life over sex and my cheast have really been bothered me extremly so I even got lung problems, and I been willing to risk the sensation for a more free way of living and then as it said it would likely come back later, i got keyhole and I can already feel my nipple very lightly even after some months I know not everyone is so lucky, but if I had to lose my whole sensation I would still have done it.
