Genital piercings are not among the most popular piercings in the world, but there are many people who enjoy them. Actually, genital piercings are probably more popular than people think. That being said, certain types of genital piercings are more popular than the others.
There are also some genital piercings that are very rare, even among genital piercing enthusiasts. Reasons are numerous. Some piercings are rare because they are located at a very sensitive spot so they are very prone to migration and rejection. Some are rare because the placement itself is not very useful: it doesn’t contribute to pleasure during sexual activities, so these piercings cannot be considered functional.
