He says that it happened right after we had sex and that he thinks I cheated and got some sort of std from cheating on him when I didn't. I don't see any stds with symptoms that match. He normally has very soft and smooth skin but as of yesterday it is very plastic feeling and very wrinkled. The scrotum is definitely more wrinkled than it should be and the shaft shouldn't be wrinkled at all. What in the world could do something like this!?
