In a group of 2,159 gynecological patients, aged 21 to 40, the age at the first sexual intercourse was ascertained and correlated with orgastic capacity during coitus in marital life. All had been married for at least 1 year. Of the examined females, 1,093 who reached orgasm mostly or always during sexual intercourse had their first coitus earlier than 394 women with rare and 165 women with no coital orgasm. The difference between orgastic women and examinees with rare orgasm was significant at the 0.01 level. The difference between females with adequate sexual reactivity and females with no coital orgasm was significant at the 0.001 level.
