What Are Normal Sexual Averages?

Sexual health is an important part of a healthy adult lifestyle. Having sex is good for us; our bodies were designed for sex. People are caught up in averages, however, and fear that they are not adequately “equipped.” This causes undue stress and a subconscious reticence to engage in healthy sexual activity. This fear is completely unfounded. To prove my point, let's look at some sexual averages.

A man's average height is 5 feet and 9 inches; average weight is 172 pounds. Average penis sizes range from 3 to 5 inches when not erect to 5 to 7 inches when erect. Men's testicles, on average, are approximately 2 inches long, with a diameter of 1.2 inches. The average man's semen has an alkaline pH of 7.0 to 8.0, and semen ejaculated contains about 300 to 500 million sperm.

Women are 5-feet, 3.5-inches tall and 143 pounds on average. A woman's vagina expands to approximately 4 inches long when stimulated, and rests at 3 inches long. Women's ovaries are usually 1.5 inches long and .075 inches wide; breasts measure in at 35.9 inches. Women release approximately 400,000 eggs throughout their lifetime, and the vagina's pH level is 4.0 to 5.0.

Thirty-four percent of married couples have sex two to three times a week on average. Seven percent of married couples are little more ambitious and have weekly sex five or more times. A whopping 95 percent of married couples were sexually active prior to tying the knot, yet 50 percent of married couples who lived together prior to marriage end up divorced.

How have these averages changed over the last 50 years? Our height hasn't really changed that much, but we've gained a lot of weight. The average woman's bust size has increased slightly, but data does not suggest any other pertinent physical changes. We are a society that is more open about sex now, so people might be enjoying sex a little more often.
