I have a prosthetic leg, so I've been getting the secondary screening (i.e. pat-downs, bomb wipes, and wanding) for years. It's invasive, but the TSA agents don't grope your genitals. They don't even touch them. In fact, they're usually shy about touching "sensitive areas" (most of the inner thigh remains unexplored), and sometimes bordering on apologetic. I get that every single time I fly, and even so, I would never opt for a backscatter machine. It's far more invasive. Having been through dozens of patdowns, I feel pretty sure that someone looking at a naked picture of me is a worse option.
