Masaail relating to intimacy

Q: Can husband and wife have relations if child e.g. six years old is sleeping on same bed?

Q: I am a new muslim and am a bit confused about certain issues concerning intercourse with one's wife. I have read fatwas and talked to recognised scholars, but I am still confused. First of all, I know that masturbating alone is haram, but what is if the spouses are not together due to travelling and while fantasizing of the spouse they touch the chest, merely to fantasize, not touching his genitals? Furthermore, to what extent is a partner allowed to touch himself/herself during intercourse? Is it true that during foreplay or intercourse I am not at all allowed to rub/touch my penis in her presence, and she is not allowed to enter her fingers in her vagina or stimulate the surroundings in my presence (from stimulating during foreplay to finishing off after sex or during menses)? If this is the case, does this refer only to the main sexual organs (penis and vagina opening) or are we also not allowed to stimulate our other parts like chests, prostata, clitoris, body, etc.? If we are allowed, does this count only during penetrition/intercourse or during the whole act of sex (during foreplay, can each partner touch his/her permissible parts to arouse himself/herself or arouse the partner; can a woman suck, lick her breasts to arouse herself and as a pleasure for her husband). Secondly, sheikh mohammad bin adam al kawthari, permits the use of toys under certain conditions, such as not using it on the main genitals (penis and vagina opening) to resemble masturbation; thus is there anything wrong with wearing a massage (vibrating) glove during mutual masturbation on the main privat parts and intercourse, as it is the hand one is using and not a toy? Can one use it on one's own permissible body parts (not to masturbate in case this is forbidden, see question 1). I prefer it as it prevents touching vaginal fluids by hand and does not resemble a male genital. Thirdly, if my wife wants me to spank her during intercourse, either by using my hand or a stick, is this allowed and to what extent? Not with the intention of resembling non-muslim habits or hurting her, merely because it arouses her and myself. Fourthly, as my wife has an African origin, her hair is not as easy to handle as smoothe hair. Thus is it allowed for her to wear a wig or extensions only for me during intercourse? Could you explain in detail as I have read different opinions (from permission to prohibition and curse by ALLAH).

Q: Is a major sin for a couple to look at the private parts of each other?

Q: I was shocked after reading this fatwa from a whabbi site, can you please validate and answer this question:

Is it permissible for a man to have intercourse with his wife without a cover? Is it permissible to have intercourse in the bathroom? 

Praise be to Allaah.  

Yes, it is permissible for a man to have intercourse with his wife without a cover, and it is also permissible to have intercourse in the bathroom, but that means that he will be going against the Sunnah by not mentioning Allaah beforehand. Perhaps you know that the Sunnah, when a man wants to have intercourse with his wife, is to say, “Bismillaah, Allaahumma jannibna al-Shaytaana wa jannib al-Shaytaana ma razaqtana (In the name of Allaah, O Allaah, keep the Shaytaan away from us and keep the Shaytaan away from that with which You may bless us).” Perhaps you also know that it is not right to mention the name of Allaah in places where you relieve yourself, so how can the one who has intercourse in the bathroom recite this dhikr? Unless he is going to go out, recite this dhikr and then go back in.

I remember reading some masla or a hadith that its discourage to spend unnecessary time in the bathroom / toilets.
