Not feeling attracted to women

Q: My son is 23 years old and a hafez ul quran. We have been talking to him about getting married and after many months he has now confided to his mother that he does  not feel attracted to women but perhaps more to a man. He assures her that he has not done anything wrong and he has been looking for Duas to pray to help him overcome this illness. Can you help please urgently?

Masturbation

Q: The act of masturbation is defined as rubbing ones private parts to reach climax and this is not allowed in Islam. Now my question is, is it wrong if a person without touching his privates reaches climax, for example, bouncing on ones bed facing towards the roof with the intention of climaxing yet not touching the genitals. Would this be termed as 'masturbation' and is it wrong Islamically?

Asking for a separation

Q: My husband is having an affair with other women, which he refuses to break relations with. He is a very abusive man who abuses me emotionally, mentally and physically. We have 2 children together who have witnessed all the abuse. Do I have grounds for a divorce and what are they?
