Of course there are! The oldest symbols have emerged in the Girlfag Livejournal community initiated by Clare T. Rampling and are used a lot since.
So far so good. However, there are also GF/GD who cannot (fully) agree with the Venus and Mars symbol because they don’t have a binary gender, they might be trans, non-binary, genderqueer, bigender, (cis)genderfluid, etc. To make non-binary GF/GD visible, Paul’a aka Tochter Kampfstrumpf has designed different variants.

A combination of the (old) genderqueer flag and the girlfag symbol:
While these flags show that there are non-binary GF/GD, the Venus and Mars symbols will still erase non-binary GF/GD. So the idea came to combine the genderqueer/non-binary symbol, which you see on the right, with the Venus and Mars symbol.
This is how this variant originated. The color selection is just like in the genderqueer flag and the asterisk on the Venus symbol is a placeholder for non-binary genders.
It shows that girlfags are mostly women, but not always/not exclusively female.
And, of course, this is just the opposite for guydykes!
Max* has created flags, according to this template, which are very nice to look at and very well designed. Therefore, they are used as a standard on this website. Thanks Max*!
