Cheating or not

Jackie

So my man told me something and I said to him that he cheated on me he said that's not cheating. He told me that his co-worker put on diffrent lingerie for him to see and he saw each of them. He said that's not cheating. He also said I'm overreacting. To me that's cheating bec he had no right to see another woman body like that. What do yall think
