Sex Calculator

This isn’t just another gimmicky “love calculator” — it’s a science-inspired, fun, and surprisingly accurate tool that combines real anatomical data, exercise physiology, and a dash of playfulness to give you meaningful (and entertaining) insights about sexual activity.

How Each Metric Is Calculated

• Sexual Compatibility Score (0–100)
  Based on peer-reviewed studies of erect penis length/girth and aroused vaginal dimensions. The calculator evaluates: - How well lengths align (ideal: penis slightly longer than vaginal depth when aroused) - Comfortable girth-to-width ratio (too tight or too loose both reduce comfort) - Uses weighted scoring with real population distributions
• Calories Burned
  Uses official MET (Metabolic Equivalent of Task) values from Harvard Health and the Compendium of Physical Activities: - Gentle ≈ 2.8 METs - Medium ≈ 3.8 METs - Intense ≈ 5.8 METs
  Example: 30 minutes of passionate sex can burn as many calories as a 20-minute jog!
• Pleasure Score
  A playful blend of duration, intensity, and compatibility. Longer sessions with good fit and higher energy generally feel better — science and common sense agree.
• Fun Fact Generator
  Every calculation pulls a new, verified sexy fact from medical journals, Kinsey Institute reports, and large-scale sexual health studies.

Scientific Sources We Rely On

• Veale et al. (2015) – BJU International meta-analysis (15,521 men)
• Herbenick et al. (2014) – vaginal dimensions & arousal changes
• Barnhart et al. & Pendergrass et al. – gynecological imaging studies
• Harvard Health Publishing – MET values for sexual activity
• Kinsey Institute & Durex Global Sex Surveys – behavior & satisfaction data

Important Reminders

Have fun, stay curious, love fiercely, and remember: great sex isn’t about the numbers — it’s about the connection.
