Besides the wonderful comments by real experienced members this thread is pretty silly. First off, did this guy tell you or did he just go with it when one of your "friends" mentioned his size to you and you asked him? There typically is a misconception when a girl sees it, since they typically think things are large since they are small, their internal scales are different. In any case... don't you think if you came to LPSG wouldn't you say the experts are definitely here since this would attract people of such a predicament? And yet when questioned about your accuracy you think its jealousy... sounds like you're trying really hard to get a reaction when we really don't care. You also mention how you thought it was pretty common... so this site being what it is, if we say that's unlikely why wouldn't you believe us? It is because you are being untruthful or defensive for w/e reason and are a complete troll.
also love how you use inb4 in one of your posts. Its a dead give away you frequent troll forums.
