Is this a hickey?

Is this a hickey?
My boyfriend claims this is not a hickey, but I have had several friends point it out and say something where in response I tell them it’s not a hickey and I didn’t give it to him, they give me a weird look. I’ve caught him talking to his ex in the past and have a serious gut feeling something is going on even though he insists it’s not. When I bring it up he doesn’t get angry or defensive. (Then again he’s not that type of person) I don’t know what to think. HELP
