I do so agree. I'll read most anything if the style or storyline grips me, but PWP is a special case, and so to a degree, for the reasons you set out, is angst/emo. If it's about (a) physical bits and (b)emotional reaction, then I'm going to choose what has the most of the latter, which is m/m, and the physical bits that turn me on, which is also m/m.

It's also a matter of difference. I have no objection to women's bodies, or emotions, but they don't exactly come as a surprise or revelation to me either. Been there, got that.
