For the next time, you can refuse to go through the scanners. If they require a pat-down, insist on someone of the same sex. You can even insist on a private room, (though I would prefer to be touched in a place where their actions would be scrutinized by other passengers). Don't let them bully you into anything. I have to fight with them every time I fly to have my film checked. If they get cranky, just insist louder. I always go through the scanners, but when whisked in the past, TSA has never crossed any lines even remotely, and it was always done by someone of the same sex who explained everything carefully.

It's a far more respective system than a lot of the South Asian security lines, in which you are whisked far away from your belongings into the female-only groping and wanding tent, where they play with your hair and ask all sorts of relevant terrorist questions such as 'You are skinny, are you an athlete?', or 'When is your birthday? I see.. do you have children yet?', or ask you to explain your choice of jewelry. The standards for what is 'ok' in that room are so off the charts different that just remembering my experiences there makes my eyes open wider and jaw drop open in speechlessness...
