I was always self concious about my penis. I didn't want to take showers in high school gym or use public restrooms. I didn't even lose my virginity until I was 21. But what boosted my confidence was this:
-When the first girl I ever got with saw my penis, she said "Nah uh. I'm not messing with you. That's too big."
-When the second girl I ever made sweet, sweet love to saw my penis, she said "I don't know who you thing you fucking with that big ol' thang!"
-And, when the third girl I ever had sex with saw it, she gave me a big hug!!
I'm not making any of this up!! From that point on, I've been full of confidence!
