The normal duration of human sexual intercourse falls within a specific empirical timeframe
Empirical studies confirm that the duration of human sexual intercourse and related physiological markers fall within specific, measurable timeframes.
The claim is specific and falsifiable, passing Step 0. The retrieved literature contains multiple clinical and physiological studies measuring the duration of sexual intercourse, erection times, and ejaculatory latencies using specific empirical metrics like stopwatches and latency timers. Therefore, the claim is supported by the provided evidence.
