Piper made a lot of good points. Too many guys probably get worked up over the fantasy of it, but when the reality sinks in......well, they can't handle that. I would just add a few more points about that. I suspect many guys also get performance anxieties. If they are meeting a favorite sex goddess like Piper, they may be afraid they won't make the grade. Either popping far too fast or not being able to finish. Even if they are not meeting someone special to them they still can have anxieties over the cameras or other people, especially other guys, being there too. That can add up to a lot of stress.
