If she starts shouting and writhing wildly during the act, and you're left wondering how in the world you managed to make a woman so damn happy, you should sound the alarm.

The general reaction you’ve gotten in the past has been notably more subdued, and now you’ve got a woman shouting dirty nothings into your ear as you go at it in the same manner as usual? You may be tempted to brush off the thought and assume that all that practice has finally made you perfect. But, real talk: Unless you’ve drastically altered your game, she’s putting on an act. If women don’t usually swoon and scream when you enter the building, it’s not likely to happen out of the blue. Pack up your tool kit. It’s time to go home.
