I don’t expect —in an entitled sense—to ever receive nudes from a stranger. Being naked and pretty is how you cut to the front of the line, not a requisite for admission.
I expect —in a predictive way— to receive nudes sometime around the point where you realize I deserve to see all your flaws.
Also, faces have a better track record than boobs. But I’m also pickier about them, so enjoy that minefield.
