She's so frustrated she can't go out and bring back some randomers just like usual, just shows how they're struggling:

"If I just happened not to have sexual contact with another human for the duration we’ve been in lockdown (28 days), it would seem mildly bothersome, but acceptable. A predictable outcome of someone who increasingly chooses sleep over sex. But now that the law prevents me from going out and finding someone to have sex with, I’m so deeply frustrated, I think about sex more than I do whether or not to go downstairs and make myself another tea. Which is to say, a lot. When I go to the shop and catch eyes with a guy, I find myself fantasising about pushing him against the snack aisle and kissing until our jaws stiffen and our lips bruise. I scroll through Instagram profiles and everyone seems so much hotter than I remember, especially now they’ve shaved their hair off."
