That internal burning, sore feeling of the penis when you ejaculate too many times in one day.

The two states of being are as a human being, or a hungry ghost. Semi-regularly you need to ask yourself which you are. Sometimes it is human. Others, alas, it is hungry ghost.

The hungry ghost seeks validity outside of themselves. Someone pining for an indifferent ex is a hungry ghost. Someone who arrives alone at 6:30 on Saturday night to a pub is probably a hungry ghost. Obsessive checking of mobile phones, chat sites or networks are clear signs that one is a hungry ghost.

The best thing to do is just stay home and ride it out. Read a book. Find some good clean fun.

Your penis being rubbed raw from prolonged or vigorous unprotected sexual activity

When you get a handjob with no lubrication.

after you finish whacking it really hard and your urethra burns for like a half hour

Slapping a girl acrossed the forehead with your penis and leaveing a red mark

The hair that grows along the sides of your cock shaft if you don't trim down the bush.
