Does one sexual identity have a greater likelihood of sexual pleasure then another? A study by the Kinsey Institute for research of sex and gender at Indiana University Bloomington has found that lesbians are the most likely of any group to experience orgasms.
The study entitled “Variation in Orgasm Occurrence by Sexual Orientation in a Sample of U.S. Singles” surveyed 6,151 single and sexually active men and women, from ages 21 to 65. The researchers found that lesbian women had the highest frequency of orgasms at 75% of sexual experiences resulting in orgasm. The lowest likelihood of orgasm was found in bisexual women at 58%.
The correlation between rate of orgasm and sexual identity was not demonstrated in men. However, men orgasm 85% of the time regardless of sexual orientation or identity, whereas adjusting for sexual orientation, women orgasm only 62% of the time.
The institute’s founder Alfred Kinsey, pioneered research in sexual pleasure as a scientific pursuit, and noted as early as the 1950s, a correlations between sexual orientation and orgasm, however this is the first attempt to codify Kinsey’s theories.
Scientists next hope to find whether a mental or physical differentiation is responsible for the variations in likelihood of orgasm. Very little is known outside of a purely physiological level—the increase of heart rate and changes in blood pressure. The mental and emotional aspects of stimulation remains something of a mystery to researchers.
