I DID have a psych professor who insisted EVERYTHING every day, every where revolved around sex. He literally talked about Joe Camel, telephone poles, ice in Coca-Cola adverts, train tunnels... as if it was all porn. I challenged him often in class until one day he asked me to stay after. He asked me directly so I told him, I had heard he lived with his mother, and had a habit of crashing student events to hit on girls. I told him I felt he was sex obsessed and I doubted his capacity to teach the class. I was allowed a late class transfer, so that worked out cool.
From a psych professor, that doesn’t surprise me at all.
I think I had the same professor!
