There Is Plenty of Gay Sex in Karachi, Pakistan - The Wire
From the article :
But it isn't all technological cruising, either. There's good old-fashioned cruising, too, which happens at some of Karachi's most touristy spots. For example, the city's busiest shrine, Abdullah Shah-Ghazi.
Azhar writes:
Every Thursday evening, as the sun sets, men from across the city gather there. A tightly packed circle is formed and those in the centre of the circle are groped by those on the periphery.
To outsiders it looks like a writhing mass of men huddling around one another. Some even describe it as a "mysterious religious ceremony". For participants, it's anonymous group sex.
