Satisfaction (sexual, life, relationship, and mental health) is associated directly with penile-vaginal intercourse, but inversely with other sexual behavior frequencies.

Abstract in brief

• The study found that the frequency of penile-vaginal intercourse (PVI) is positively linked to sexual satisfaction, overall life satisfaction, partnership quality, and mental health, implying that more PVI generally leads to higher satisfaction.
• Conversely, higher frequencies of masturbation and noncoital sexual activities are associated with lower satisfaction levels, suggesting these behaviors are inversely related to well-being and sexual fulfillment.
• The findings indicate that PVI has a unique and beneficial role in sexual and mental health, and the negative correlation with masturbation is not simply due to lack of PVI, highlighting the specific importance of penile-vaginal sex for overall satisfaction.]
