100 pound weight loss, plan on loosing another 100 pounds. Will I need multiple skin removal procedures over time? (Photos)

Hello. I have lost sbout 100lbs of fat and plan on losing snout 100lbs more. It's been about 4 years of stsbke weight since the initial loss and my skin has proven it is very inelastic and does not recover well. Should I get a skin removal surgery now, lose more weight, and get another one? Or wait until I've lost all the weight I plan on? i am doing a lot of strength training and will be gaining size again in the future, but I would like my skin to be tight. Please let me know your thoughts. I am considering panniculectomy, gyno surgery, and skin removal for my thighs and buttocks (along w fat transfer the buttocks ideally). or perhaps a 360 would be better? My goal result is a full, masculine chest, tight round belly, and full backside. Thank you for your input.
