OK, so I have a bisexual, platonic lady friend of many years who has never expressed any interest in me, and in fact has shot me down in the past. Last night, I hung out with her and her girlfriend watching movies. The girlfriend who was staying the night had already gone to bed, and I was saying my goodbyes to platonic lady friend. who hugged me and kissed me on the cheek like she's done many times before. Then she bit/sucked my earlobe. Now, if she was single and hadn't shot me down in the past, I'd know what this means. If her girlfriend was also bisexual, and not an out-and-out lesbian, I'd know what this means, (not my kind of thing, BTW). Since neither of those things are the case, I don't know what this means. Does it mean anything? Does it just mean she'd had too much to drink?
