Weak and ridiculously easy to top:
Ridiculously shy guy and his ridiculously shy girlfriend are about to have sex for the first time. Since they are both ridiculously shy, they turn off the lights, take off their clothes and lie naked next to each other on the bed, waiting for the other to initiate the good stuff. Finally, ridiculously shy guy decides to be a man and do something about it. He asks his girlfriend, "Stick out your left hand." Trembling, she does so. He takes her soft, shaky hand and places it on his penis. She grips it and says, "We better save the cigarette for after the sex."
