No it doesn't. Pual or John, not positive which one it was, but they speak of being caught up to the third heaven. So it would seem that the NT supports there being different levels of heaven. Have not really prayed or focused on this issue in my studies of the bible. So this is pure speculation with some evidence.
I hope that people are not promised boys in heaven, that would be pretty sick. But the concept of 70 virgins does entice the flesh. Muhammad, being a man with many wives probably thought this was a seductive offer for those who were willing to follow his teachings. Think about it, a lustful man will love a promise of 70 virgins that he can have. Most men today, would love to have 70 women, but is that Godly or heaven like.
In the Bible, it says that we will be like the angels in heaven, to my knowledge, a spirit does not have need, nor is it able to have sex, but could be wrong (never asked God do spirits have intercourse).

Do you really think the Koran does not contradict itself?
