It throbs becouse it fills with blood when he gets a erection and your heart pumps the blood so when it throbs it becouse his hearts beating. If you listen to his heart beat and watch it at the same time when you hear his heart his dick will throb. It doesnt always throb though he has to have a really hard erection

You have to think that penis becomes hard because at once a right amount of blood flows in it and has to stay until the stimulus is on. You know that blood is pushed by heart and as you feel throbbing touching any artery, all the more so you feel that touching a hard co.ck.... ok?

heartbeat. the penor is a sac of blood vessels. the heartbeat is magnified by this structure. hence the penor throbs.

Your heartbeat. If your hard enough, the veins have to pump more blood and so they do it to the beat of your heart.

Sexual desire makes his penis throb and harden into an erection.

he wants to have sex with you when he does that. or he is thinking about a girl he saw on a porno site.
