Men seem to put so much emphasis on penis size- sh1t fucks with them when it's small. But I can't really talk as I'm in the "above average" department (over 7.5" and nearly 6 inches around when fully erect) so I've never worried about it. I do have a friend who has really low self-confidence because he's smaller than average (like 4.5 inches and thin). But it sounds to me like the ladies say it doesn't really matter. I can say that my playmates haven't all been able to handle anal because of my size so that's a plus for you "effective" folks.
