That if you are a stone butch or stone femme you are not a lesbian. That just gets the big

from me. Not all stone butches and stone femmes are lesbians, but there are plenty that are. There is no conflict.
On a related but more general topic many people, including many butches and femmes, seem to think lesbian sex is narrow in scope when in fact lesbians have sex in as many ways, shapes and forms as any type of person. Kinky, vanilla, stone etc. Just because there usually is not a male involved (although at times there are) doesn't make lesbian sex or sexuality limited or narrow or leave a bunch of things out or make us less sexually fulfilled, adventurous, etc.
