There is nothing wrong with sex. In fact, the Prophet (Allah bless him and give him peace) himself explained that one is rewarded for fulfilling one’s desires in a lawful manner with one’s spouse.
It is permitted to read ‘respectable’ discussions of sexual advice. The condition for the permissibility of reading such matters is that:
a) The content not be of a perverse or inappropriate nature;
b) One does not look at the unlawful;
c) One does not think about that which is haram (such as individuals other than one’s lawful spouse); and
d) It does not lead one to do the haram (such as masturbate, even if later).
sites have good material that does not contravene the first 2 conditions.
The other two return to the individual.
The Human Soul
Allah swore by a long list of oaths in the Qur’an regarding the soul:
091.001 By the sun and his brightness,
091.002 And the moon when she followeth him,
091.003 And the day when it revealeth him,
091.004 And the night when it enshroudeth him,
091.005 And the heaven and Him Who built it,
091.006 And the earth and Him Who spread it,
091.007 And a soul and Him Who perfected it
091.008 And inspired it with its wrong its right
091.009 He is indeed successful who purifies it,
091.010 And he is indeed a failure who stunts it.” [Qur’an, Surat al-Shams]
Imam Sulaiman al-Jamal explains these last two verses in his Hashiyat al-Jalalayn [4.542] by stating that this success of the soul is by purifying it from bad deeds and being busied by good deeds; its failure, stunting, and abasement is through by sins.
This is why the Messenger of Allah (Allah bless him & give him peace) said, “Fear Allah wherever you are; follow a bad deeds with a a good one and it will wipe it out; and deal with people with excellent character.” [at-Tirmidhi, from Abu Dharr and Mu`adh ibn Jabal (Allah be pleased with them)]
Abu Malik al-Ash`ari reported that the Messenger of Allah (Allah bless him & give him peace) said, “Purity is half of belief. 'Praise be to Allah' fills up the balance, and 'Glory be to Allah and praise be to Allah' fills up everything between the heavens and the earth. The prayer is a light. Charity is a proof. Steadfastness is an illumination. The Qur'an is a proof for you or against you. Everybody goes out and trades with his own self, either setting it free or destroying it.” [Muslim]
And Allah alone gives success.
