On my one trip to Egypt, I agree that the young men seemed very sexy & either curious or very horny.
One day on the Cairo Metro, I was waiting on the platform at Tahrir Square with an Egyptian guy on crutches. The train arrived, we both got on but there were no seats. There were 2 nice-looking, young (early 20's), tall, fit guys who were sitting down & next to them a sour-faced gent in gray clerical garb. The older guy gestured to the 2 young guys & one guy stood up & gave his seat to the guy on crutches. The young guy then sat down on the lap of his friend & they were still sitting together like that when I got off the train!
