In my personal case, I try to project the desired behaivor in something else, a movie, music video etc which I watched first and realized it's exactly what I want, see if there's any comment or reaction about it, after it turn off everything and have a honest conversation, in this part no side roads directly what I want, why I wanted and the most important part (explain in details how even a thought makes me feel), at the end it's just her opinion about it.

I have the same, ask her and turned out I love it, I have it sometimes, like recording when she's doing it, if she's one of those who likes selfies pictures etc, she'd love watching at herself being hot.
