Lots of lesbians are interested in actually being able to see people like themselves perform on camera. Even in the Information Age, this is somehow difficult for them to find. Mainstream pornography does have so-called lesbian porn. However, in almost all cases, the so-called lesbians are straight women who are pretending to be attracted to one another for the delight of an assumed heterosexual male audience.
Many straight men love watching 'lesbian' porn, and they might even be interested in watching porn that features real lesbians. However, lesbians don't want to watch straight women pretending to be into each other on screen, because they can usually tell the difference. Many straight men don't really notice or care about any of that, since they get to watch two attractive women going at it and that tends to be what matters to them. They have never experienced lesbian sex, obviously, so they probably won't pick up on the lack of authenticity. Since men will tend to sexualize physical fights between women, they can clearly fill in the gaps themselves when it comes to lesbian porn that was made by straight men and for straight men.
Lesbians who actually have experience with lesbian sex will see the situation differently. They want to see women like them practicing the moves that they might want to try and the moves that they have tried. Lesbian cams can be the answer for them.
There are lots of great options when it comes to lesbian cams. Lesbians will often be able to see real couples doing their own thing in the context of lesbian cams. This can actually give them the chance to experience it all vicariously. Vicarious experiences are almost impossible in the case of porn that looks overly fake. People can't really insert themselves into a scene when it looks like the scene is going to be impossible to do in real life, or if it's not the sort of thing that anyone would want to do in real life at all.
One way or another, lesbian cams offer authenticity. The women who participate have real experience. Some of them might be bisexual or pansexual. They're actually having sex with girls on the camera and they can offer people of a similar orientation the kind of experience that they would never have been able to get in the old world of mainstream professional hardcore porn.
A lot of porn like this will be less objectionable to lesbians who are much more politically minded and who have a problem with some of the output of professional hardcore porn. They're just sharing a sexual experience with other women with the whole world, and this can make all the difference in the world for the women who are sick to death of what they used to find in the older Internet world. Lesbian cams will overlap with other types of cams of course, depending on the participants. All lesbian cams should be united in their authenticity.
