Maybe this is easier if you've had a sister. I never did. And I can't sit across the table from a skin-flashing admin assistant and think of her like my mom, who is in her 70s. It doesn't work.
The fact that you use the term "skin-flashing" here is a little concerning. Perhaps it was just meant as a shorthand for attractive woman, because otherwise you've taken a woman's choice of dress and behaviour and made them part of your neurosis. Unless of course she is giving you the Basic Instinct treatment (is that too old a reference for this site?), in which case I'm entirely out of advice for you.
