Nikaah & Marriage Issues

Wife claiming that her first husband did not divorce her

Q: After married to a second husband for 20 years, the wife declares that she is no longer married to the 2nd husband because she was never divorced from the first. The 1st husband reclaims his wife. In the 1st marriage, no talaq was mentioned. The husband just stayed away from the husband. Is this allow in sharia and was the second marriage valid. What's the ruling on this?

Homosexuality

Q: I am gay man and don't know how to handle this situation with my religion. I am not sexually attracted to women and wanted to know if there is a way for me to be with a man? Or do I have to keep fighting against my sexuality? I hope you can help me.

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?
