Do we retain our gender in Heaven? The Bible tells us repeatedly that our earthly actions will impact our ability to enter the gates of Heaven. Some Biblical passages say that our earthly actions can improve or lessen our experience of Heaven if we are in fact lucky enough to reach it.

With that being said, I conclude that we must retain our earthly identities and our earthly experiences. But if that's the case, then I must ask:


Do we retain our gender in Heaven?


Reason for my question:  

A person's gender shapes their experience on planet Earth. Gender is a quality that you simply cannot shake. It opens some doors and closes others (and I'm not talking about the rest rooms :/) On the other hand, the Bible describes Heaven as a state of perfection and a place without bounds. As I see it, gender creates bounds, or at least a lane within which to operate. Such a lane would seem to run contrary to the nature of Heaven.
St Augustine says we do and I might as well quote him at length since its way way in the public domain:

Whether the Bodies of Women Shall Retain Their Own Sex in the Resurrection.
From the words, Till we all come to a perfect man, to the measure of the age of the fullness of Christ, Ephesians 4:13 and from the words, Conformed to the image of the Son of God, Romans 8:29 some conclude that women shall not rise women, but that all shall be men, because God made man only of earth, and woman of the man. For my part, they seem to be wiser who make no doubt that both sexes shall rise. For there shall be no lust, which is now the cause of confusion. For before they sinned, the man and the woman were naked, and were not ashamed. From those bodies, then, vice shall be withdrawn, while nature shall be preserved. And the sex of woman is not a vice, but nature. It shall then indeed be superior to carnal intercourse and child-bearing; nevertheless the female members shall remain adapted not to the old uses, but to a new beauty, which, so far from provoking lust, now extinct, shall excite praise to the wisdom and clemency of God, who both made what was not and delivered from corruption what He made. For at the beginning of the human race the woman was made of a rib taken from the side of the man while he slept; for it seemed fit that even then Christ and His Church should be foreshadowed in this event. For that sleep of the man was the death of Christ, whose side, as He hung lifeless upon the cross, was pierced with a spear, and there flowed from it blood and water, and these we know to be the sacraments by which the Church is built up. For Scripture used this very word, not saying He formed or framed, but built her up into a woman; Genesis 2:22 whence also the apostle speaks of the edification of the body of Christ, Ephesians 4:12 which is the Church. The woman, therefore, is a creature of God even as the man; but by her creation from man unity is commended; and the manner of her creation prefigured, as has been said, Christ and the Church. He, then, who created both sexes will restore both. Jesus Himself also, when asked by the Sadducees, who denied the resurrection, which of the seven brothers should have to wife the woman whom all in succession had taken to raise up seed to their brother, as the law enjoined, says, You do err, not knowing the Scriptures nor the power of God. Matthew 22:29 And though it was a fit opportunity for His saying, She about whom you make inquiries shall herself be a man, and not a woman, He said nothing of the kind; but In the resurrection they neither marry nor are given in marriage, but are as the angels of God in heaven. Matthew 22:30 They shall be equal to the angels in immortality and happiness, not in flesh, nor in resurrection, which the angels did not need, because they could not die. The Lord then denied that there would be in the resurrection, not women, but marriages; and He uttered this denial in circumstances in which the question mooted would have been more easily and speedily solved by denying that the female sex would exist, if this had in truth been foreknown by Him. But, indeed, He even affirmed that the sex should exist by saying, They shall not be given in marriage, which can only apply to females; Neither shall they marry, which applies to males. There shall therefore be those who are in this world accustomed to marry and be given in marriage, only they shall there make no such marriages.
St. Augustine - City of God - Book 22 chapter 17 

So, to summarize, yes there are sexes, no there's no sex because:

There's nothing wrong with being a woman
Jesus would have made it more clear when saying folks aren't married in Heaven.

Now, I'll bet your wondering if women have beards in heaven? Well that's another question, but somewhere in there I belive he even answers that.
