This obsession with virgins has dominated the mentality of many Muslims and is behind much of the repression of women in Islam.
Even liberal Muslims sometimes suffer from this mentality that sees a woman as 'spoiled' or 'loose' if she is not a virgin or refuses to cover herself up.
You mean, when I get to heaven, I can't see their faces because they'll be covered up? How do I know if I even am attracted to them all? Or if they're all really female?
No thanks Allah, I'd rather eat this delicious ham and cheese melt for breakfast, and do other haram things.
Don't worry, the scriptures have already stated what you will do to them:
Bukhari vol.6:402: "The statement of Allah, Beautiful fair females restrained in pavilions. Narrated Qaisi, Allah's Apostle said, 'In Paradise there is a pavilion made of a single hollow pearl sixty miles wide, in each corner there are wives who will not see those in the other corners; and the believers will visit and enjoy them(all).'"
Quran 55:56: "In them will be (Maidens), chaste, restraining their glances, whom no man or Jinn before them has touched"
I'd still rather have just this life, and one wife. Even one is hard sometimes, let alone 72, most of which will be sexually deprived, and moody because of it.
