Hmmm, i know a few lesbians, and the sarge is right on some of his points.
The majority of lesbian relationships have one of them being more 'manlike'.
I have asked this question years ago ,and they say its the persona they are attracted to.
They also say when it comes to sex, they prefer the intimacy and each say they like the rough and smooth, just as with a man. I will see some out tomorrow night and i think i am gonna ask this question again, when i a drunk.
The majority of lesbians though have all had failed relationships with men...
Make of that what you will.
