Overview

• The analysis examined data from more than 400,000 UK adults aged 39 to 73, with about 1 percent reporting never having had sex.
• Those without lifetime sexual experience reported higher loneliness, greater nervousness and lower happiness than sexually experienced peers.
• Male respondents in this group were more often physically weaker and tended to live in regions with fewer women.
• Roughly 15 percent of the differences between sexually experienced and inexperienced adults were attributed to genetic factors such as variants linked to intelligence or neurodevelopmental traits.
• The study also found lower alcohol and drug use and higher childhood rates of wearing glasses in the never‑had‑sex group, and it did not distinguish voluntary from involuntary sexlessness.
