I’ve seen a lot of unusual piercings over the last thirteen years. However, I think of all rare piercings, the rarest may well be the hymen piercing (among other things, most women who go for genital piercings are sexually active already). The example in this entry (click here for an unpierced before shot) was done by Ralf at Visavajara in Freiburg, Germany (one of my favorite towns in Germany), and it is only the second example of one that I’ve seen.
I am afraid I do not know the stories behind either of the two piercings… In the case the customer didn’t say why they wanted the piercing, and Ralf didn’t pry. I can think of a million interesting reasons for these, but I don’t know which of them it is.
