You guys are being self defeating. Ok, so we're all here because we are seeing what we can do about making our cocks bigger, right? So we probably have (or have had) a bit of an inferiority complex around our size. But look, if we take that inferiority thing into a relationship, we are doomed to failure.
Then, there's this 'good girl v bad girl' thing. C'mon, this is the 21st century. Women are liberated. They are entitled to have an exciting sex life before they get married. Surely that's the healthy way forward. If it's good enough for you, why not them? Now, be honest; isn't the reason why you don't like the thought of going with sexually experienced girls simply based upon the idea that they are bound to have had bigger dicks before you came along? If you start throwing the stupid idea around that 'experienced girls are sluts' you have got to expect girls to defend themselves the best way they can; ie. by getting at your 'Achiles' heel - your inferiority complex regarding your penis size. In other words, you are causing the problem you should be trying to solve. Go into a relationship, or just a quick one-nighter, with a generous spirit towards the girl, and you might just be surprised by the nice feedback she'll feel like giving you.
Does anyone get what I'm trying to say here?
