Did you even read Cmanns post or are you purposefully try to provoke a fight in chat? Cmann clearly only talked about the applicability and complications of implementing the tags and potential asinine discussions. Those type of discussions you are trying to arouse out of people. Better to let it go, I'd say.I'll save you the time, i'm a lesbian and never touched a dick. Please do teach me about my sexual orientation though, that never fails to amuse.
Regarding your actual issue of not finding the content you're looking for, I'd guess look for the lesbian tag in conjunction with a female protagonist. You probably will have a higher hit percentage with that.
