AbuMusa narrated in Abu Dawud #2080 The Prophet sallallahu alayhe wa sallam said: There is no marriage without the permission of a guardian.
Aisha, Ummul Mu'minin narrated in Abu Dawud #2078 The Apostle of Allah sallallahu alayhe wa sallam said: The marriage of a woman who marries without the consent of her guardians is void. (He said these words) three times. If there is cohabitation, she gets her dower for the intercourse her husband has had. If there is a dispute, the sultan (man in authority) is the guardian of one who has none.

Uqbah ibn Amir narrated in Sahih Al-Bukari #3.882 Allah's Messenger sallallahu alayhe wa sallam said, "From among all the conditions which you have to fulfill, the conditions which make it legal for you to have sexual relations (i.e. the marriage contract) have the greatest right to be fulfilled."
AbuHurayrah narrated in Sahih Al-Bukari #7.67 The Prophet sallallahu alayhe wa sallam said, "A matron should not be given in marriage except after consulting her; and a virgin should not be given in marriage except after her permission." The people asked, "O Allah's Apostle sallallahu alayhe wa sallam How can we know her permission?" He said, "Her silence (indicates her permission)."
AbuHurayrah narrated in Sahih Muslim #3274 Allah's Messenger sallallahu alayhe wa sallam said: A man must not make proposal of marriage to a woman when his brother has done so already. And he must not offer a price for a thing for which his brother has already offered a price; and a woman must not be combined in marriage with her father's sister, nor with her mother's sister, and a woman must not ask to have her sister divorced in order to deprive her of what belongs to her; but she must marry, because she will have what Allah has decreed for her.
Ubayy ibn Ka'b narrated in Sahih Al-Bukari #1.292 I asked Allah's Apostle sallallahu alayhe wa sallam about a man who engages in sexual intercourse with his wife but does not discharge. He replied, "He should wash the parts which comes in contact with the private parts of the woman, perform ablution and then pray." (AbuAbdullah said, "Taking a bath is safer and is the last order.")
Umm Sulaym narrated in Sahih Muslim #0608 Umm Sulaym asked the Apostle of Allah sallallahu alayhe wa sallam about a woman who sees in a dream what a man sees (sexual dream). The Messenger of Allah sallallahu alayhe wa sallam said: In case a woman sees that, she must take a bath. Umm Sulaym said: I was bashful on account of that and said: Does it happen?

Man's discharge (i.e. sperm) is thick and white and the discharge of woman is thin and yellow ; so the resemblance comes from the one whose genes prevail or dominate.
