The average duration for penetrative vaginal sex typically ranges between 3 to 7 minutes, with research showing about 5.4 minutes on average before ejaculation. According to surveys of sex therapists and studies, sexual intercourse lasting 1 to 2 minutes is considered too short, while 10 to 30 minutes is considered too long. Most experts classify 7 to 13 minutes as the desirable duration for penetrative sex. However, "sex" can be defined differently by each person. Some include foreplay, oral sex, and other intimate activities in their definition, which lengthens the overall experience. Foreplay alone often lasts 5 to 20 minutes and contributes significantly to sexual satisfaction. Importantly, the ideal length of a sexual encounter varies greatly depending on individual preferences, physical and emotional connection, and the types of sexual activities involved. The key is having a satisfying experience rather than focusing on the clock. In summary:

• Penetrative sex average: ~5.4 minutes
• Too short: less than 2 minutes
• Adequate: 3–7 minutes
• Desirable: 7–13 minutes
• Too long: 10–30 minutes
• Including foreplay, total sexual encounter time can be longer and varies widely

Sex should primarily be pleasurable and mutually satisfying, regardless of exact timing.
