pre-release safety-check

Refers to either:
(1) Where you ask a gal if there would be any chance of her getting pregnant before you "let go" inside of her, or
(2) Where --- prior to your letting go of a door and allowing it to close again after you've been holding it open for one or more persons passing through --- you briefly duck your head around said door to make sure there aren't any other people heading for the doorway, thus avoiding your accidentally letting the door slam in the faces of these previously-unobserved folks.
Clueless dude, speaking plaintively to a social-advice counsellor: I always make a point of performing a pre-release safety-check before I let go of a door after holding it open for others; it just seems like a lot of times, the folks who are inside the house or store yell at me to "not let the heat out" or "not let the bugs in". Well, what da HECK am I SPOSTA do --- just blindly let da door slam shut again and risk bruising someone's face?!
Counsellor (gently and seriously): Oh, nooooo --- of course not. I would suggest standing inside the doorway so that you can see both inside and outside at the same time simply by turning your head; that way, you can check for stragglers during the final few seconds while the last person is entering/exiting the room, and thus it will not take any extra time to be safe.
