hotmilf, I'm sure it isn't that lesbians necessarily hate cock, but it just doesn't interest them. As for why they would use cock-shaped objects: I'm guessing that it's because the shape is very utilitarian, but it's not attached to a man.
I'm sure there would be a few 100% lesbians on the site if they were aware of what the site is really all about. There are often topics in Etc Etc that could be of interest to anyone of any age, gender, or orientation.
The title just doesn't really give that much information or inspiration.
