AbuSa'id al-Khudri narrated Sahih Muslim #3369 Allah's Messenger sallallahu alayhe wa sallam said: The most wicked among the people in the eye of Allah on the Day of Judgment is the man who goes to his wife and she comes to him, and then he divulges her secret. (discussing what she does in bed)
Jabir ibn Abdullah narrated in  Sahih Muslim#5190 Allah's Messenger sallallahu alayhe wa sallam said: There should be a bedding for a man, a bedding for his wife and the third one for the guest, and the fourth one is for the Satan.
Abdullah ibn Abbas narrated in Sahih Al-Bukari #6.103 He stated regarding the Divine Verse:- 'O you who believe! You are forbidden to inherit women against their will, and you should not treat them with harshness that you may take back part of the (Mahr) dower you have given them.' (4:19) (Before this revelation) if a man died, his relatives used to have the right to inherit his wife. One of them could marry her if he would, or they would give her in marriage if they wished, or, if they wished, they would not give her in marriage at all. They would be more entitled to dispose of her than her own relatives. So the above Verse was revealed in this connection.
AbuHurayrah narrated in Sahih Al-Bukari #7.27 The Prophet sallallahu alayhe wa sallam said, "A woman is married for four things, i.e. her wealth, her family status, her beauty and her religion. So you should marry the religious woman (otherwise) you will be a loser."
Uqbah ibn 'Aamir stated that the Prophet sallallahu alayhe wa sallam said "The best marriage is the simplest one." (This statement was made than the Prophet sallallahu alayhe wa sallam officiated a marriage, after  asking the man and the woman if they wanted to marry the other, without questioning about the dowry.   (Collect by Abu Dawud #2112, authetnic in S.J.S #3300
AbuHurayrah narrated in  Sahih Al-Bukari #7.113 Allah's Apostle sallallahu alayhe wa sallam said, "The woman is like a rib; if you try to straighten her, she will break. So if you want to get benefit from her, do so while she still has some crookedness."
The couple is encouraged to engage in foreplay before having intercourse.  The Prophet sallallahu alayhe wa sallam supposedly said: One of you should not fall upon his wife like the way an animal does, let there be a merger between them.'  He was asked: ' And what is the messenger?  He said: 'Kissing and talking." -Related by Al-Daylami) This indicates that the man should seek to satisfy his wife's desires as she satisfies his. (** the authenticity of this hadith is not known, and Allah knows best)
  Abdullah narrated in Sahih Al-Bukari #7.4 We were with the Prophet sallallahu alayhe wa sallam while we were young and had no wealth whatever. So Allah's Apostle sallallahu alayhe wa sallam said, "O young people! Whoever among you can marry, should marry, because it helps him lower his gaze and guard his modesty (i.e. his private parts from committing illegal sexual intercourse etc.) and whoever is not able to marry, should fast, as fasting diminishes his sexual power."
