Also, at what stage is the physicality of a budding relationship more poignant and more immediate and incremental than in high school? I wasn't a late bloomer in high school, but neither was I a porn star. The memories I have of the physical aspects of my high school relationships is so tame and restrained compared to what it would be for me now, or even what it would have been for other kids I went to school with.
For me, at the time, pictures like this, with a lot of emotion, a lot of quiet passion, and even a bit of sexual innuendo (however faint) would have made me smile for days.
