Breast Augmentation at Mid 20's - Philippines, PH

I'm happy with the result but the raised scar is bothering me. I'm thinking about undergoing scar revision for it maybe by june . I've tried everything "dermatix", even the laser, it seems not to have any improvement. I talked to my doctor about it, he said he would do it for free which im thankful about however im afraid. Anyone who has experienced about scar revision?

I'm happy with my boobs however i'm concerned with the scar. It looks like it's going to have keloids. I've been putting contractubex to reduce the risk. Any experience about this? Do u think this will be gone after many months :'(
Another thing, i tried to have sex one time and I felt no sensitivity at my nipples at all. I had to fake it. Omg! Is thia normal?

I'M massaging it and hopefully if finally drops like normal boobs. CANT WAIT TO SEE THE RESULT:)
