Does this look like a cum stain to you?

This is a pic of the inside of his pants. I have never seen a stain like this on any of his pants. He recently went to a wedding and I was doing his laundry and found this. His tie was also in his pant pocket. When I confronted him about it he said “it’s always been there” then he got all mad and said “get tf out of my house I didn’t cheat on you!” He was also half asleep I woke him up to ask him. he literally just bought this suite days before the wedding??? And who tf would buy pants with a cun stain on it!!?? Ladies please help. Please. I’m so upset right now I’m seeing red. Does it look like a cum stain to you??
