Masaail relating to intimacy

Anal sex

Q: My question is what to do if my husband ask for anal intercourse? It is notable that he is suffering from satyriasis which is known as sex addiction according sex therapist. So if he can't get cured from this, is it permissible for wife to ask for a divorce? Husband keeps saying that he will commit suicide if the wife leaves him?

Being considerate to one's wife in regard to sexual relations

Q: I'm a high school girl and I have some questions about some things written in my Islamic studies book. There is a verse that goes "Whenever a man calls his wife to his bed and she refuses and then he passes the night in an angry mood, the angel curses her till she gets up at dawn" It is also written repeatedly that a woman must be sexually submissive to her husband and she may not even fast without his permission because he cannot have intercourse with her while she is fasting. This greatly distressed me. Allah is the most Fair and Knowing and I know I couldn't begin to understand His reasoning. However I'd like if you could explain to me why there doesn't seem to be the concept of consent on a woman's behalf in marriage. The common claim that "men get more sexually frustrated" does not seem to be enough as I think that he should still take in account his wife's consent and if he is abusive because of this that is no excuse.

Delaying in consummating the nikaah

Q: I have a topic I would like to speak about that I've been trying to read upon but simply can't find anything about it. I recently got married alhamdulilah. Me and my wife spend a lot of time together and alhamdulilah we're looking for a house as soon as possible but I have a feeling we won't consumate the marriage (intimacy) till a long time down the line. I'm just not a sexually active person. I adore my wife and enjoy my time with her so much that sex is never on my mind and she is the same. Is it haram or wrong to wait till the perfect time even if it takes 3-6 months to have sex? 

Fantasizing about other women

Q: I am married to my cousin (mother's side) 6 years ago.This was a pure arranged marriage and neither of us had any likeness apart from the fact that we were cousins before marriage. We both try to make salaah on time and we take care of each other as well.

My question is that what does Islam say if a husband has no physical attraction towards his wife despite so much efforts to feel attracted to her but still no feelings. During intercourse he only gets aroused sexually by imaging other women. Otherwise its not possible for him to get arouse sexually.

Kindly guide me what to do as this is killing me from inside. I don't know how long I can live like this. Besides this we have no arguments and no fights. She takes good care of me and I do the same, but it's only this one thing and it's happening for more than 5 years. What should I do?
