Fact check: How long should the first round of sex last

1. Summary of the results

Based on the research analyses, there is significant variation in what constitutes typical duration for sexual intercourse. Multiple studies reveal different timeframes:

• Average penetration to ejaculation time: Research consistently shows 5-7 minutes as the average duration from penetration to male ejaculation ^{[1] [2]}, with some studies extending this range to 5-11 minutes ^[3].
• Professional therapeutic perspective: Sex therapists surveyed defined "adequate" sex as lasting 3-7 minutes and "desirable" as 7-13 minutes ^[4].
• Longer duration studies: Japanese research found significantly longer average times, with estimated mean intromission times of 14.5 minutes for males and 13.6 minutes for females ^[5]. Another study reported mean time to female orgasm at 13.41 ± 7.67 minutes ^[6].
• Female satisfaction correlation: Research indicates that women's consistency of orgasm is associated with longer duration of penile-vaginal intercourse but not with foreplay duration ^[7].

2. Missing context/alternative viewpoints

The original question lacks several crucial contextual factors that research reveals as important:

• Cultural and individual variation: Studies show significant variations among individuals and cultures in sexual duration expectations ^[3], suggesting that cultural background heavily influences what is considered "normal."
• Definition ambiguity: There is no consensus on what constitutes 'sex' - whether this includes foreplay, multiple activities, or just penetration ^[1], making the question inherently difficult to answer definitively.
• Age and relationship factors: Research indicates that factors such as age, relationship status, and individual preferences significantly affect duration ^[3], meaning the "first round" concept may vary dramatically based on these variables.
• Medical considerations: The analyses reveal that premature ejaculation is a common issue that can be treated with various techniques and medications ^[2], suggesting that some individuals may need medical intervention to achieve desired durations.
• Unrealistic expectations: Popular culture's portrayal creates unrealistic expectations that can lead to disappointment ^[4], indicating that societal pressure may distort natural sexual experiences.

3. Potential misinformation/bias in the original statement

The original question contains several problematic assumptions:

• "Should" implies normative judgment: The question assumes there is a universal standard for sexual duration, when research clearly shows this varies dramatically between individuals, cultures, and relationships.
• "First round" assumption: This phrasing suggests that multiple rounds are expected or normal, which may not reflect many people's sexual experiences and could create performance pressure.
• Male-centric framing: The question appears to focus on male performance metrics rather than mutual satisfaction, potentially overlooking the research showing that female orgasm consistency is associated with longer durations ^[7].
• Oversimplification: The question ignores the complex interplay of factors including foreplay, emotional connection, communication, and individual preferences that research shows are crucial to sexual satisfaction.

The pharmaceutical and sexual wellness industries would benefit from promoting anxiety about sexual performance duration, as this drives sales of treatments, supplements, and therapy services.
