Female sexuality from all studies that have ever been conducted on the subject is rather more flexible than male sexuality. Women who sleep with women tend to have had relationships with men as well, so jokes about lesbians who are only lesbians because they need a good dicking or because she just came out of a bad relationship tend to be broadly accurate - there's a reason why things become cliches. There are a small percentage of women who are much more similar to men than women in terms of their hormonal balance who will be happy to never see a penis, but for most, lesbianism is a sort of reactionary response.
That in mind, considering the lesbian domestic violence epidemic, the lesbian obesity crisis, and the prevalence of lesbian bed death, while what you're saying is technically correct, it's also not very reliable. Women who choose the lesbian lifestyle are much more likely to get abused, get incarcerated, get fat, and become incels, so in the end giving themselves completely to a good man is a woman's best bet for being fulfilled in life.
