BTW, I roomed with a Muslim female once, then recently converted to Christianity, while in college. I know the stories they tell.
This was art, and should be protected as such.
As for lesbianism and wearing fancy underwear beneath a burqa, that is unlikely to be true in any Muslim group other than young women in countries where gender segregation is ruthlessly enforced, e.g. Saudi Arabia.
Is the fancy underwear thing unlikely due to a desire for simplicity, like the Amish? That excessive decoration and unnecessary extras are detremental to the lifestyle where you should be thinking and living for God? Or is it because of a overbearing culture that would enforce punishments if they did?
