If you're girlfriend, wife, etc tells you that one of their previous bf's, lovers, etc had a 9 inch penis, they're probably exaggerating. For example, My penis is 6.5 inches. Nothing to really brag about. Before my wife and I got married, her and her best friend were talking about sex and my wife blurted out that I have a big penis. Her friend was curious, so asked, "How big?" My wife told her 9 inches. This was a disaster. Her friend, who was also supposed to be her Maid of Honor at the wedding, kept emailing me, calling me, and wanting to hang out with me. She ended up coming clean to my wife that she wanted to sleep with me/have a threesome with us. My wife kicked her out of the wedding. This was 4 years ago and still, to this day, she emails me asking me to see my penis.
