I've not had surgery, but it may be worth knowing that there are advantages to having surgery both pre and post testosterone. High oestrogen levels mean your skin will be softer and scars will lighten faster. Being on testosterone for over a year gives your body shape/fat redistribution a chance to settle down, and also gives you time to build muscle. Good pectorals will give the surgeon something to work with and usually means you get a more accurate nipple placement, with the scars hidden on the underside of the pecs.
It's all worth considering, but when you're in the first year of T, you don't really get either of those advantages unless you fancy working your ass off for the pecs.
