You know you made a mistake if.
She doesn't return calls, just texts back. Turns out her smoking habit or something has made her voice sound like she's twice her age.
Every text from her is just 2 or 3 words. Then later you realize that the session is also the bare minimum.
She opens the door and you see no resemblance to the photos on her ad. You didn't follow advice on this site, of course.
While waiting for her to actually do something, you cannot figure out what genre the blaring show on the TV is part of.
PSE seems to stand for Pathetic Sexual Experience.
You say you want to use a condom and get a blank look.
An anorexic provider is spending half your time bending over her cell phone and you think, "doggie?" then think, no "Whippet", "Italian Greyhound"?
You hurry so much afterward to get out of the strong cigarette smoke you put your undershorts on backward.
