I'm sending this all because it can also affect in conceiving child :
There are no particular rules and laws either in foreplay or in intercourse. The only laws and rules are the ones reached by the lovers by mutual and often unspoken understanding. Whatever is pleasing and satisfying to both the husband and the wife is right and proper; and whatever is mutually displeasing is wrong. The only limitation to this general rule would be any Shariah rule, which goes against the wishes of the husband or the wife.
A. Foreplay is Highly Recommended:
Islam emphasizes on foreplay. Imam Ali (as) says, "When you intend to have sex with your wife, do not rush because the woman (also) has needs (which should be fulfilled)." Sex without foreplay has been equated to cruelty. Holy Prophet Muhammad (s.a.w.) said, "Three people are cruel: .a person who has sex with his wife before foreplay."
Another hadith equates sex without foreplay to animal behavior: "When anyone of you has sex with his wife, then he should not go to her like birds; instead he should be slow and delaying."
As for the role of a woman in sexual foreplay, the Imams have praised a wife who discards shyness when she is with her husband. Imam Muhammad al-Baqir (a.s.) says, "The best woman among you is the one who discards the armor of shyness when she undresses for her husband, and puts on the armor of shyness when she dresses up again." After all, modesty and chastity in public is the hallmark of a Muslim lady.
These sayings clearly show that the husband and the wife should feel completely free when they are engaged in mutual stimulation, which is known as foreplay. There is nothing wrong, according to Islam, for a woman to be active and responsive during sex. As for the Islamic Shariah, all the mujtahids are unanimous in saying that the act of sexual foreplay in itself is mustahab (recommended). Likewise, it is recommended not to rush into sexual intercourse. The operative word is mutual pleasure and satisfaction.
B. Techniques of Foreplay:
As far as the methods of mutual stimulation in foreplay are concerned, the Shariah allows the husband and the wife to see, kiss, touch, smell and stimulate any part of each other's body. Therefore, oral sex, as it is known, is allowed. Imam Musa al-Kazim (a.s.) was once asked, "Can a person kiss his wife's vagina?" The Imam said, "No problem."
The only restriction is that no foreign object should be used. The restriction on the use of foreign objects is based on the following hadith. Ubaydullah bin Zurarah says that he had an old neighbor who owned a young slave-girl. Because of his old age, he could not fully satisfy the young slave-girl during sexual intercourse. She would therefore ask him to place his fingers in her vagina, as she liked it. The old man complied with her wishes even though he did not like this idea. So he requested Ubaydullah to ask Imam Ali ar-Reza (a.s.) about it. When Ubaydullah asked the Imam about it, Imam Ali ar-Reza (a.s.) said, "There is no problem as long as he uses any part of his own body upon her, but he should not use anything other than his body on her."
Though masturbation (i.e., self-stimulation of one's own sexual organ till emission of semen or orgasm) is not allowed, in the case of married persons, there is no problem if the wife stimulates her husband's penis till the emission of semen or the husband stimulates his wife's vagina till orgasm. This is allowed because it does not come under "self-stimulation;" it is stimulation by a lawful partner.
C. Sexual Intercourse:
Is there any particular position for sexual intercourse, which is forbidden in Islam? No! As far as the basic coital positions are concerned, there are no restrictions. The term 'basic coital positions' denotes the positions known as the man above, face to face, woman above face to face; side position, face to face; rear-entry position in which the husband penetrates the vagina from the rear. Actually, the Shariah has left it on the husband and the wife to explore and experiment as they wish. However, it is makruh to adopt a standing position, or to face the Qiblah or keep it on the backside during the intercourse. It is advisable to refrain from the acrobatic positions given by some sexologists of the East and the West, which might even cause physical harm.
Remember, the basic rule is mutual pleasure and flexibility. If one partner does not like a particular position, then the other should yield to his or her feelings. It is highly emphasized that at the commencement of intercourse the partners should recite Bismillaahir Rah'maanir Rah'eem (In the name of Allah the Beneficent, the Merciful).
D. Anal Intercourse:
The opinions of our mujtahids vary on the permissibility of anal intercourse. The majority of the Shi'ah mujtahids have derived two conclusions: (1) that anal intercourse is not Haraam but strongly disliked (karahatan shadidah) provided the wife agrees to it. (2) and if she does not agree to it, then all mujtahids say that it is precautionarily wajib to refrain from it.
However, during the last decade of his life, Ayatullah al-Khu'i departed from the majority view and gave the ruling that it was precautionarily wajib to abstain from anal intercourse no matter whether the wife agrees to it or not.
Maulana Sayyid Muhammad Rizvi says, "I would strongly advise against anal intercourse," and quotes the saying of Imam Jafar as-Sadiq and Imam Ali ar-Reza (a.s.) about anal intercourse: "Woman is a means of your pleasure, therefore do not harm her."
After the intercourse the partners may first wipe their genitals with clean pieces of cloth. It is recommended that the same cloth/towel must not be used by both of them.
09. DUA FOR PREGNANCY:
Imam Jafar as-Sadiq (a.s.) has taught the following dua:
Transliteration: Allaahumma laa tadharni fardanw wa anta khairul waaretheen wah'eedanw wah'sheeyan fayaqs'uroo a'n tafakkori bal habli a'afiyata s'idqin dhokooranw wa onaathan aanaso behim minal wah'shate wa askuno ilaihim minal wah'date wa ashkoroka I'nda tamaame ne'matin yaa wahhaabo yaa a'zeemo yaa mo-a'z'z'amo thumma a'at'eni fee kulle a'afiyatin shukran h'atta tabloghani minha riz"waanoka fee s'idqil h'adeethe adaaail amaanate wa waqaaain bil 'ahde
Translation: O Allah! Do not keep me solitary though You are the best of Inheritors. I am alone and terrified of loneliness. This worry has reduced my thankfulness to You. So bestow on me true forgiveness and give me female and male children so that by their company I can cure my terror of loneliness. By which my loneliness is cured. So that on the completion of this bounty I can thank You. O the greatest Giver, O the Greatest, O the Bestower of greatness, after this bestows me with tawfeeq that I thank You for every kindness. Till I can achieve Your kindness by thankfulness, by speaking the truth, by returning trusts andby fulfilling oaths
