Sex is attractive and fun but at the same time, it sure is awkward. Once while I was dry humping a girl, she sat on my boner and since she was in the mood I couldn't really say anything to her but at the same time my phallus was being crushed like Germany crushed Brazil in the last world cup. That sure was awkward, and all I could think was how do I tell this to her.
But enough about my stories. Here are the general awkward thoughts that men get when they are in bed, which should help you understand that... oh well, sitting on someone's boner is not a kind gesture.
