Masaail relating to intimacy

Q: Is oral sex allowed in Islam?

Q: Can a wife and husband masturbate each other while working away and far from each other over the phone?

Q: Is pleasuring the private part via tongue, hand classed as zinna/fornication? Is it punishable by hadd? How can one hope for forgiveness for such a disgusting sin as apparently repentance for major sin is not always accepted.

Q: I am married for one and half years. I have been blessed with a baby girl Alhamdu liallah. My husband has erection problems. We hardly have intercourse. I feel very depressed and annoyed. What should I do according to Islam? He thinks it is fine, there is no need for treatment.

Q:

1. I am wondering whether we are allowed to be in the bed with the wife for meeting purposes in the dark covered completely without any clothes?
2. Can we do such a conversation over the phone to fulfill our desire while working away?

Q: I am finding that my body is very hot. My libido is very high and hence every 2 days I desire to have relations with my wife. I feel this is too much, and I'm trying to bring this down to once a week. Is there anything I can read, or any Islamic guidance for this issue. I am not looking at haram etc, it is just happening.
