Unable to satisfy one's wife

Q: I am lecturer in physics at a govt college. In 2007 I got married and yet I remained unable to have intercourse. I have a problem of erection and discharging early. At the first night my wife was not willing to have intercourse then on her will I did not have intercourse. For many days we do oral and upper sex with each other but my wife was not willing to do intercourse and I also left it. But after 3 months we tried for intercourse but my wife got frightened and I also did not get a full erection to insert inside and discharge before inserting. This thing is going on for the next 5 months and I remained unable to do intercourse. Then I decided to take medicine and have different treatments but got no success and remained unable to insert and to get full erection and discharge early. I asked my wife to take a divorce from me as I am not able to fulfill her sex requirements but she said that she want to live with me and have treatment done. I make many attempts to do intercourse but remained unable and also take different medicines. Before marriage I never know that I have that problem otherwise I will never get marriage. Now I am in deep depression as I feel that I destroyed the life of my wife and I am committing the sin and she is not willing to take divorce but she got frustrated when I remained unable to do intercourse. Now 10 years are passed and if she now takes divorce where she will go?

Kindly help me and tell me that is my nikkah or marriage is valid?

Secondly what is the ruling of Islam for couple like us, what we should do? We are in deep trouble and depressed. My wife want to live with me and want to do intercourse with me and she has emotional attachment with me. Is it possible that I can be able to do intercourse and be able to satisfy me wife? I am in deep trouble, kindly help me to overcome this problem. 

Husband not being intimate

Q: I am very concerned about my marriage and I need help. I have been married for 5 months now and my husband has not consummated our marriage. Although, he is intimate in other ways and treats me well. I am very disturbed and embarassed to talk to him about the issue. I wanted to know how should I deal with it.

Desire for children after abortion

Q: I'm 27 years old.  I had two abortions under some circumstances which were absolutely sin and I keep asking forgiveness from Allah for it. Now, I'm married and have one baby girl of 3 years old and we want to have another baby but it's not happening anymore. I am starting to get into depression as I'm scared that this is the punishment from Allah.

I have come to a conclusion that everybody has a number of kids allotted from Allah but since I have aborted two babies and I got one so now I may not have any baby in my life anymore, is this thought correct?  But honestly when I had this baby girl the only thing I thought is that may be Allah forgave me that's why he blessed us with his most precious gift - a girl. 

Is there any kaffarra for these sins and that Allah bless me with more kids?

Breaking a promise

Q: If I made a promise to Allah Ta'ala that, if I was to be cured from this illness, I would never do a particular sin again. However when you get better you fall into that type of sin again.

Now does this mean I will be included in the verse of surah tawbah verse 75-77 who Allah Ta'ala punished with hypocrisy as a result of breaking a promise with Allah Almighty. I am really worried that I  am going to be punished with hypocrisy and die a hypocrite.

Getting money from social services

Q: I have been paying taxes for 5 years close to 1200 to 1400 dollars a Month.
