I always wondered about this too and found an online Muslim Dear Abbey Imam to who has answered the question for us.
You will probably find this highly unfair but the female suiciders only get their husband, not 72 Chippendales dancers. (Which raises the question, what happens if her husband outlives her? Or what if he is no great "reward," if you know what I mean?) Ah well, Muslim sexism persists even in the afterlife, it appears.

The Imam promises that they will be made more beautiful so that they can compete with the virgins. BFHD! LOL
Good grief. Thanks for the solid info, gutshot...GMTA, huh?
