Masaail relating to intimacy

Husband and wife viewing each other on Skype

Q: My husband and myself see each other on Skype naked at times because we are both living in two different countries separately for now. We are both very attracted toward each other with sexual desires. Is allowed for us to masturbate for each other. My husband likes to ejaculate with his hand and I finger myself. Please let us know if this is an allowed act in Islam if doing it for your spouse.

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

Q: Is it wrong to have a high sex drive? I love having frequint sex with my wife. Sometimes I want sex for one time 3 nights in a row or very seldom twice in one night and sumtimes once every second night. Mostly we have sex once every third to fourth night. She complains and has a problem with this because she doesn't want to wet her hair so often and its frustrates me if she refuses or when she finds a problem with this. Is this normal to feel frustrated what is the ruling about the amount of sex I can have with my wife?

Masturbation

Q: We are a relatively young couple and happily married with two children. One thing missing in our marriage is intimacy and sex. Its been like this for
the last 9 years. My wife has declared that she is no longer interested in this side of marriage and wants to be left alone. Sexual frustration and being faithful has been a huge battle and test so far and to keep this in check would occasional masturbation be allowed?
