Interesting point, not that I believe you (yours surely much bigger than mine!), but I was thinking about what would be interesting for the viewers.... In a roman setting, and probably a modern one to, you would love to see a barbarian crucified, so with hairy, ugly body and big, horrifying penis! Just think of all this roman ladies, who are shocked and sexually attracted by these uncivilised men- In todays world, we see most porno's with large and always (at least since viagra) erected penis views. There are naturally "special interest groups", but I guess most porn actors are manly man and naturally always ready, just like me.....Speak for yourself, I am pretty smooth and slinky! XD
Great post though. My cock is very small so perhaps my humiliation would make other men feel good about themselves.
