Long ago my partner in crime (once or twice literally...) decided it was only fair that we used pictures of men in our research too. She started with me, yep, naked except for a hat. I used to be able to find a few of those pictures on the internet, usually converted to dithered 16-color gifs, but now they've been lost in the flood of much higher resolution pictures of naked people. (I can still find slash she wrote, authorship frequently claimed by other people, which I find highly amusing because I saw her writing it. It was first passed around as Xerox copies years before most people had even heard of the internet.)
In those days we'd sometimes check out magazines from the university library for our image scanning experiments. A library clerk found out what we were doing and the next magazine she handed us had the library's "Received" stamp covering all the naughty bits.
When I was in school there were only a few women engineering majors and they were not treated well. That's one of the reasons I changed my major to biology. I didn't want to be one of those guys.
There's been some progress since, not nearly enough.
