Fish tank time 

The period of time where sex (usually heterosexual penetration) is so boring that you'd rather pay attention to the guy's conveniently positioned fish tank than actively engage in sex.

A: "Hey, I heard you and Tom hooked up last night, how'd it go? Is he worth a go?"

B: "For someone who's so experienced, there was way too much fish tank time. Would not recommend."
