'' documented that, over the previous five years of sexual activity, 78% of women had orgasms in 60% to 100% of sexual encounters with other women, compared with 55% for heterosexual sex. Kinsey attributed this difference to female partners knowing more about women's sexuality and how to optimize women's sexual satisfaction than male partners do. Similarly, studies by several scholars, including

Masters and Johnson's 1979 study on lesbian sexual practices concluded that lesbian sexual encounters include more full-body sexual contact, rather than genital-focused contact, less preoccupation or anxiety about achieving orgasm, more sexual assertiveness and communication about sexual needs, longer lasting sexual encounters and greater satisfaction with the overall quality of one's sexual life.

'', found that women in same-sex relationships enjoyed identical sexual desire, sexual communication, sexual satisfaction, and satisfaction with orgasm as their heterosexual counterparts. Additional research by Blair & Pukall (2014) reported similar findings, such that women in same-sex relationships reported similar levels of overall sexual satisfaction and lower levels of sexual frequency. However, this recent study also reported that women in same-sex relationships spent significantly longer amounts of time on individual sexual encounters - often spending upwards of two hours on an individual encounter. Consequently, what lesbians may lack in frequency, they may make up for with longer durations. With regard to the ease or difficulty of achieving orgasm, Hite's research (while subject to methodological limitations) showed that most women need clitoral (exterior) stimulation for orgasm, which can be "easy and strong, given the right stimulation" and that the need for clitoral stimulation in addition to knowing one's own body is the reason that most women reach orgasm more easily by masturbation. Replicating Kinsey's findings, studies by scholars such as Peplau, Fingerhut and Beals (2004) and Diamond (2006) indicate that lesbians have orgasms more often and more easily in sexual interactions than heterosexual women do. Preferences for specific sexual practices among female same-sex relationships have also been studied. Masters and Johnson concluded that vaginal penetration with dildos is rare and lesbians tend to perform more overall genital stimulation than direct clitoral stimulation, which is also often the case for heterosexual relationships. Concerning oral sex, the common belief that all women who have sex with women engage in cunnilingus contrasts research on the subject. Some lesbian or bisexual women dislike oral sex because they do not like the experience or due to psychological or social factors, such as finding it unclean. Other lesbian or bisexual women believe it is a necessity or largely defines lesbian sexual activity. Lesbian couples are more likely to consider a woman's dislike of cunnilingus as a problem than heterosexual couples are, and it is common for them to seek therapy to overcome inhibitions regarding it. Some lesbians practice

. In 1987, a non-scientific study (Munson) was conducted of more than 100 members of a lesbian social organization in Colorado. When asked what techniques they used in their last 10 sexual encounters, 100% reported kissing, sucking on breasts, and manual stimulation of the clitoris; more than 90% reported French kissing, oral sex, and fingers inserted into the vagina; and 80% reported tribadism. Lesbians in their 30s were twice as likely as other age groups to engage in anal stimulation (with a finger or dildo). A 2014 study of partnered lesbian women in Canada and the U.S. found that 7% engaged in anal stimulation or penetration at least once a week; about 10% did so monthly and 70% did not at all. In 2003, Julia Bailey and her research team published data based on a sample from the
