Sexual Relationships: Advantages, Disadvantages, and Frequency Data
A new study reveals that sexual activity can have numerous benefits, such as improved sleep, immune function, and reduced cortisol levels. One of the key factors contributing to these benefits could be the number of sexual partners one has.
Research suggests that having multiple sexual partners may increase the release of endorphins, which help fight cancer cells and infections. This could potentially lower the risk of fatal heart problems, prostate cancer, and breast cancer. However, it's important to note that having multiple partners also increases the risk of HIV exposure or transmission.
A 2021 research found that the timing of partnerships may link to an increased likelihood of contracting a Sexually Transmitted Infection (STI). A gap of 4 months or more for women and 6 months or more for men reduces the risk of an STI diagnosis.
Regarding the average number of sexual partners, the Centers for Disease Control and Prevention (CDC) reports that the median number for women is 4.3, while for men, it's 6.3. However, these numbers can vary significantly across age groups, with younger generations tend to have more sexual partners than older generations.
A 2025 survey found that the average number of partners for older adults (54 to 72 years) was 7.4 for women and 12.9 for men. Generation X (38 to 53 years) reported an average of 10.1 partners for women and 16.1 partners for men. Millennials (23 to 37 years) averaged 10.8 partners for women and 13.4 partners for men.
In Great Britain, median lifetime partners vary by age, with adults aged 40 to 59 having the highest median of 6 partners. Young adults (18 to 29 years) report a median of 1 partner, likely reflecting shorter sexual histories.
Ethnicity and sexual orientation influence demographics but specific averages are less clear from the available data. Regarding sexual orientation, about 89-90% identify as heterosexual, with smaller percentages identifying as gay, lesbian, or bisexual. Studies show homosexual and bisexual populations tend to be younger and more often male, which may influence sexual partnership patterns.
Income and employment status also play a role in sexual activity levels, indirectly impacting lifetime partner counts. Higher sexual inactivity rates occur among unemployed, part-time employed men, and students. Higher income individuals may have different sexual behavior patterns, but precise average partner numbers by income were not detailed in the search results.
It's crucial to remember that safer sex practices are essential when engaging in sexual activity with multiple partners. Using a condom or a dental dam every time, having regular STI testing, using condoms on sex toys, and washing toys before and after each use are strategies for safer sex.
In conclusion, the average lifetime number of sexual partners increases with younger generations and is higher among men than women. Ethnicity and sexual orientation influence demographics but specific averages are less clear from the available data. Income and employment status affect sexual activity levels, indirectly impacting lifetime partner counts. It's essential to prioritise safe sex practices to minimise the risks associated with multiple sexual partners.
