Americans tend to start having sex in their teens or early 20s.

Sexual frequency and number of sex partners also tend to be highest between 20 and 29, particularly for those in relationships who have a partner available.

Key Statistics To Know:

  • 46.7% of men aged 18 to 44 and 53.3% of women in that same age group reported having sex weekly or more often in the past year. [5]
  • Men aged 25 to 49 years old had a median number of 6.3 opposite-sex partners and women in that same age group reported having a median partner count of 4.3. [4]
  • 99% of men and women report having sex by the age of 44, and 95% had done so before marriage. [6]
  • On average, married couples in America have sex around 55 times per year. [8]
  • One study of married heterosexual couples in America showed that 23.2% of men and 19.2% of women cheated on their current partner. [10]
  • By age 19, about 70% of teens have had penile-vaginal intercourse at some point in their lifetime. [12]
  • A 2023 study of university students 18 years or older found that 45.5% were in a committed sexual relationship, 18.2% were in a casual sexual relationship, 4.5% were in a sexual relationship with more than one partner, and 30.8% had no current sexual relationship. [13]
  • Americans in their 20s report having sex an average of 80 times each year; those in their 30s report having sex an average of 77 times per year; those in their 40s have sex an estimated 63 times per year; those in their 50s report having sex an estimated 38 times per year; and those in their 60s report having sex an average of 20 times per year. [8]
  • Among men and women aged 75 to 85 years old, 54% reported having sex as frequently as at least two to three times per month. [17]

Over time, sexual frequency tends to decline — stress, hormones, mental and physical health, trauma, and relationship issues are common reasons.

Importantly, however, quality does not necessarily equal quantity!

In this article, we’ll explore sex statistics including frequency and partner counts by age, gender, and relationship status.

Latest Statistics On How Often People Are Having Sex

  • 46.7% of men aged 18 to 44 reported having sex weekly or more often in the past year. [5]
  • 49.9% of men aged 35 to 44 reported having sex weekly or more often during the past year, compared to 50.3% of men aged 25 to 34 and 37.4% of men aged 18 to 24 who reported the same. [5]
  • 53.3% of women aged 18 to 44 reported having sex weekly or more often in the past year. [5]
  • 53.3% of women aged 35 to 44 reported having sex weekly or more often during the past year, compared to 54.2% of women aged 25 to 34 and 52.1% of women aged 18 to 24 who reported the same. [5]

Overall, roughly half of adult men and women aged 18-44 tend to have sex at least weekly, if not more often.

Younger men, however, have sex a bit less often which may relate to relationship status, religiosity, and/or work/school responsibilities.

Average Number Of Sexual Partners Over A Lifetime

  • In 2002, 23.2% of men aged 15-44 reported a lifetime count of fifteen or more sexual partners [1], compared to 21.6% by 2006 [2], and 21.1% between 2011 and 2015 [3].
  • By contrast, in 2002, 9.2% of women in the same age group reported having 15 or more sex partners in their lives [1], staying relatively consistent at 9% between 2006 and 2010 [2], and increasing to 10.1% between 2011 and 2015 [3].
  • From 2015 to 2019, however, men aged 25 to 49 years old had a median number of 6.3 opposite-sex partners, and women in that same age group reported having a median partner count of 4.3. [4]

On average, men tend to have a higher number of sex partners than women, though of course individuals can vary widely.

Cultural or religious norms, spontaneous vs. responsive sexual desire, prioritizing of emotional connection, and concerns about or history of assault are several reasons for this difference.

Of course, there’s no competition — do whatever (or whoever) works best for you!

Most Recent Statistics On Sex Before Marriage

  • According to one study that included men and women, 99% of all respondents had had sex by the age of 44, and 95% had done so before marriage. Even among those who abstained from sex until the age of 20 or older, 81% engaged in premarital sex by age 44. [6]
  • 65% of the American public views premarital sex between committed adult partners as acceptable. [7]

While sex before marriage was once taboo, now it has become the norm.

Later age at marriage (or forgoing marriage at all), higher education levels, reductions in religiosity, the advent of birth control, and changing cultural norms are several reasons behind this shift.

Latest Statistics On How Often Married Couples Are Having Sex

Married couples have sex approximately 15% of days in a year, compared to unmarried couples having sex on about 16% of days.

Roughly the same percentage have been sexless in the past year, with slightly fewer being sexless for 5 years.

Most Recent Statistics On Partner Infidelity

bar graph depicting that 23.2% of men and 19.2% of women report cheating on their current partner while married
  • One study of married heterosexual couples in America showed that 23.2% of men and 19.2% of women cheated on their current partner. [10]
  • In Western countries, between 25 and 50% of divorces are primarily caused by partner infidelity. [10]
  • 23.4 % of American men and 15.5% of American women in dating relationships physically cheated on their partner sexually. [11]
  • 15.3% of men and 4.6% of women reported cheating on their partner through online means, with no physical involvement. [11]

Infidelity is common, though that doesn’t make it any less devastating.

What is considered “cheating” can vary from person to person, so discussing your views with a partner is important to avoid any misunderstandings.

The Latest Statistics On Teenage Sex

bar graph depicting that among teens aged 15 to 19, 54% of females and 52% of males reported having at least one sexual experience (penile-vaginal sex, oral sex, anal sex, or a sexual experience with a same-sex partner)
  • About half of teens (54% female, 52% male) have had some type of sexual experience between the ages of 15 and 19 (penile-vaginal sex, oral sex, anal sex, or a sexual experience with a same-sex partner). [12]
  • By age 19, about 70% of teens have had penile-vaginal intercourse at some point in their lifetime. [12]

About half of teens are engaging in sexual behavior, but that certainly doesn’t mean “everybody’s doing it”!

Some act out of their own sense of desire, though undoubtedly peer pressure and cultural norms play a role as well.

Sexual Activity In College (Current Statistics)

  • A 2023 study of university students 18 years or older found that 45.5% were in a committed sexual relationship, 18.2% were in a casual sexual relationship, 4.5% were in a sexual relationship with more than one partner, and 30.8% had no current sexual relationship. [13]
  • 38% of college students reported “always” using a condom during sex; this group had an average of 12.74 sex partners. [14]
  • 15% of college students reported “never” using a condom during sex; this group also reported an average of 17.95 sexual partners. [14]

Relationships (romantic or sexual) are common in college, though many stay more focused on their studies as well.

Concerningly, those who never use condoms have the highest number of sex partners, which makes the spread of STIs and unplanned pregnancies a much greater risk.

Sexual Activity During 20s: Most Recent Statistics

bar graph depicting that among gen z adults through the age of 24, 54.1% of men and 55.4% of women report that they had vaginal sex in the past 30 days

  • 55.4% of women aged 18 to 24 reported having vaginal sex in the previous 30 days, compared to 62% of women aged 25 to 29. [15]

Sexual activity tends to be highest in one’s 20s, particularly later in one’s 20s when the likelihood of being in a committed relationship increases.

Latest Statistics On Sexual Activity In 30s

Sexual frequency is still quite high amongst individuals in their 30s, though sex may slow down a bit while approaching one’s 40s.

Sexual Activity In 40s (Most Recent Statistics To Know)

While great sex can still be enjoyed in our 40s, this is the age range when things often slow down.

Erectile dysfunction and female sexual issues start becoming more common at this age as well.

Latest Statistics On Sexual Activity During 50s

bar graph depicting that among men and women aged 50 to 59, 32% engage in partnered sex weekly, 28% engage in masturbation weekly, and 22% engage in oral sex weekly
  • Among men and women between the ages of 50 and 59, 34% report having sexual intercourse weekly, 28% report engaging in masturbation weekly, and 22% report engaging in oral sex (giving or receiving) weekly. [16]
  • Americans in their 50s have sex an estimated 38 times per year. [8]

By our 50s, we’re typically having about half the sex we did in our 20s.

Menopause becomes a common issue in this stage, as do erectile issues.

Sexual Activity During 60s (Latest Statistics)

bar graph depicting that among men and women aged 60 to 69 who reported engaging in sexual activity on a weekly basis, 26% reported having partnered sex, 22% reported masturbation, and 18% reported having oral sex

Sexual frequency reduces substantially in our 60s, having about half the sex as those in their 50s.

Simultaneously, many older individuals report feeling more comfortable in their skin and some can be more accepting of their desires.

Sexual Activity After Age 70: Current Statistics

donut chart depicting that 54% of those aged 75 to 85 report having sex at least two to three times per month
  • Among men and women aged 65 to 80, 65% reported that they are still interested in sex. [18]
  • Among men and women aged 75 to 85 years old, 54% reported having sex as frequently as at least two to three times per month and 23% reported having sex as frequently as once per week or more. [17]

Contrary to stereotypes that sex ends when we go gray, many 70+ year-olds still like to have a good time.

It may look a bit different from sex in one’s 20s, but the happiest couples prioritize physical intimacy in whatever ways work best for their particular situation.
