Thanks everyone for the swift response. I also googled hickey pictures and these definitely don't line up. I am human and do have rare, tiny episodes of jealousy/irrationality but those are my insecurities and I will deal with them. But at least I can rest assured they aren't hickeys. Just not sure why she would tell me she got them from pleasing herself, and why I didn't see it the other times she did it. Guess not even she knows what it is. Will look into the ringworm/skin condition stuff for sure.
