My experience is that large size is a wow factor and a badge of honor for some ladies, i.e. bragging rights. However, going through college with an average length dick, but one that was thick, my best reputation was due to the fact that I just loved to give oral. I had girls coming to me and saying that her mate had told her that if they asked me back for coffee then I was not going to pressure her into full sex, but that she 'really needed to try him'. Easy for me, I learnt so much about female orgasms, and how hard it is to get some girls over the cliff. It was not for want of trying on my part and, of course, with some it progressed to penetration. However, if you just concentrate on who has the biggest cock, then you really are missing out on half the fun
