Good point, but it's a pretty common "fetish" (not even sure you'd call it that) to get excited seeing normal or normally non-lewd girls get naked. Especially famous women. It's why sites collecting movie clips from Hollywood sex scenes are popular, despite hardcore porn being available. The porn stars are nobodies.

Once the technology has become more accessible, I bet it will be common for young guys to make porn with their classmates and teachers. Not even girls they have a crush on, just random girls at their school. Kind of a creepy thought actually.
