Hello, I'm new but I saw this and was in a similar situation so I feel compelled to reply. I'm 21 years old, and I too lost a lot of wieght and had a ton of loose skin that wasn't going anywhere. I had it since I lost the weight when i was 15 so its not like it was gonna tighten on it's own or anything. I am planning on having children in the future, and I was thinking I should probably wait but, i worked so hard to loose all the weight and feel comfortable in my own skin, only to be left with the loose skin. I also got implants when was 19. I know that eventually when I have kids it will stretch back out, but who knows when that will be. I want to enjoy my body while i still can and I went ahead an had the tummy tuck in may. I feel so much more comfortable in my clothes, out of my clothes with my boyfriend, and im 100% happy with my decision. When I have babies in the future I can go ahead an do it all over again. That is just my opinion, to go ahead and go for it. Good luck with evertything !
