First of all anyone who attempts to place a PA in the glans needs to have their generative organs removed. A PA passes through the wall of the urethra in the area near the frenum. It is easy and virtually painless if it is done using a needle receiving tube.
Second, a PA hurts about as much as a bee sting. Clit hood piercings hurt. They can hurt a lot. A piercing of the clitoris, proper is incredibly painful. The penis and the clit have about the same number of nerves. Think of the size difference and one can easily see the huge level of intensity of a true clit piercing.
Third, if people are ignorant regarding genital piercings, they need to educate themselves before considering such a thing.
Fourth, this area of the human anatomy is not a good place for amateurs and hacks who spend their career piercing eyebrows and ears to mess with.
