No, it would be permanent relief. Trust and believe, I've been at this going on 6 years, and at my age, I know myself quite well. There is no risk other than coming out of anesthesia, and I know I'll feel like a million bucks with crap that I thought wasn't going to happen during puberty #1 being GONE, GONE, GONE! I always expected pecs, and when these things showed up, I hated them instantly. My story spans 63 years, hun. I know who I am and what I need.
I don't have body integrity dysphoria. I am a man with the wrong body. LOL
Bottom surgery is quite different for me, because I'm a perfectionist and don't like all the faux pas of only 2 surgeries we can have. Human transplants would be the answer for that, but it won't happen in my lifetime, that I am sure. Too many religious nuts not wanting it to happen and not furthering science to bring it about.
