Well, if I didn't like big dick, I wouldn't have joined this site. But as for your first question, it's more than a matter of just size for me. If I am to be intimate with someone, there needs to be a deeper connection other than "Oh you have a big dick, let's fuck!" If I don't desire you for more than penis, what's the use? I consider that to be just porn and there are a bazillion porn sites to get that from.
