Frequency and satisfaction are different results
Studies of cannabis and sex have measured several things: how often people have intercourse, how satisfied they feel and whether particular aspects of sexual function change. These outcomes are not interchangeable. A person can report more frequent sex without reporting better function, and a satisfaction score does not measure fertility. Two widely cited studies illustrate what the research actually recorded.

A large population analysis
A 2017 US study analysed 28,176 women and 22,943 men from a nationally representative reproductive-age sample. More frequent marijuana use was associated with more frequent sexual intercourse. The analysis described a population-level relationship, not an experiment assigning cannabis to improve someone’s sex life. Its size makes it informative about reported behaviour, but it cannot determine whether cannabis caused the difference or whether other characteristics of users contributed.
What 373 women reported
A 2019 study surveyed 373 patients at one obstetrics and gynaecology practice;127 reported cannabis use before sexual activity. Those reporting such use had higher adjusted odds of reporting satisfactory orgasms. Participants also described changes in desire and pain, while lubrication generally did not change. This pattern is more specific than saying cannabis improves every aspect of sex: different domains produced different reports.
The useful interpretation
The surveys identify experiences and associations worth investigating, especially the distinction between desire, sensation, pain and orgasm satisfaction. They do not establish a standard cannabis treatment for sexual dysfunction or a predictable effect for an individual. Relationship context, expectations and pre-existing preferences can affect self-reports. Clear, ongoing consent remains independent of any claimed benefit: feeling closer or less inhibited is not a substitute for a partner’s voluntary agreement and capacity to make that decision.
