Good news from Hong Kong:
Hong Kong’s government on Monday caved in to a challenge against its gay sex laws, effectively lowering the homosexual age of consent from 21 to 16.
South Africa just needs to change their laws now. Currently, the age of consent for two males is 19, two females is 18, and male and female is 18 and 16 respectively. I think it should be 16 all round.
(Edited in 2007 to say that South Africa finally equalised the age of consent to 16.)
