Jos lesboseksi on niin hyvää, niin miksi lesbopariskunnat harrastavat seksiä vähemmän kuin homot ja heterot?

"Among couples in the first two years of their relationships, 67% of gay couples, 45% of heterosexual couples, and 33% of lesbian couples had sex three times a week or more. The numbers drop off somewhat with time: for couples who had been together 10 years or longer, 11% of the gay couples, 18% of the heterosexual couples, and 1% of the lesbian couples were having sex that often."

Onkohan se seksi sittenkään niin hyvää lesbosuhteissa?
