Studies on the prevalence of vaginal-only orgasms
Most studies do not point to a single universal preference: research finds wide variability in women’s attitudes toward the timing and characteristics of male ejaculation, with a plurality reporting n...
Current sex research rejects a simple binary that pits “vaginal” against “clitoral” orgasms and instead portrays orgasms in people with vulvas as multimodal events produced by integrated anatomy, vari...

Researchers studying “vaginal” versus “clitoral” orgasms most often rely on using explicit definitions and validated psychometric tools—asking women to classify the route of stimulation (clitoral, vag...
Laboratory and survey research have attempted to measure how long it takes women to reach orgasm under different types and sites of stimulation; early laboratory timing found mean s around 20 seconds ...
Across multiple large self-report surveys and psychometric studies, combined clitoral and vaginal stimulation is commonly reported to produce stronger, more consistent, or more likely orgasms than vag...
Combined clitoral plus vaginal stimulation is consistently reported to increase the likelihood and reliability of orgasm compared with vaginal penetration alone and is commonly cited by women as their...
Functional imaging shows both shared “orgasm” circuitry (reward, limbic, brainstem and cerebellar regions) and stimulation‑specific differences mapped in the somatosensory cortex: direct clitoral, vag...
