In "Islamic Republic of Iran" it's a crime for anyone who sleeps with someone else outside a marriage relationship. However what islamic fundamentalists are suggesting is something called "SIGHEH" (Concubine) which allows individuals to be in somehow a version of short marriage (from a few hours to a few days or weeks) and thus be allowed to have sex. The above picture is from a local newspaper in the holy city of Mashhad. (Where the holy shrine of Imam Reza is located)
The Registration office related to "SIGHEH" is asking for girls (virgins & non-virgins) from 12-35 years olds to come and register if willing to participate in this type of relationship with male pilgrims of the hole shrine.
It has even indicated a price for different durations of each relationship:
5 Hours: 50$
1 Day: 75$
2 Days: 100$
3 Days: 150$
4-10 Days : 300$
Furthermore it has even mentioned that an amount of extra 100$ will be paid to virgins for losing their virginity
One more final interesting fact is that it asks for parent's written permission for those below 14 years of age
