A new study by a Spanish gay rights group reports that about 10,000 gay marriages have taken place since Spain legalized gay marriage in 2007.
Spain has about 30 million people in 2008 over the age of 15. If 3 percent of the population is homosexual, that would be about 900,000 gay and lesbian adults. So 20,000 gay people have chosen to marry so far -- about 2 percent of gay adults. Why so few?
