Nikaah & Marriage Issues

Touching one's mother after masturbating

Q: I have a question with regards to hurmut mussaharah. Unfortunately, I was watching porn/masturbating one evening, where suddenly my mother entered the room. Although I did not expose myself in anyway, I was greeted and touched whilst I was still in an excited state from the haram I did. I remember feeling something inappropriate and trying my best to suppress the feeling, although I have no such feelings at all normally (sorry for going into detail, but I remember I still had an erection before they entered and there was a feeling after the touch which was out of my control). I also remember warmth from the touch. Has hurmut mussaharah taken place? Please advise me what to do.

Taking a second wife

Q: I have two questions to ask A) If a muslim husband if found to have had illegal sex with a christian woman as he fell in love with her, can his wife permit and support the woman to change her religion to islam and marry him? B)A wife wants to do sterility surgery in order to stop delivery as she has 3 little kids. But her husband did not permit her to do so. After that the husband chooses a second wife and abstains from sex with the first wife so that they wont have kids anymore. Whats the ruling regarding such a case in Islam?

Oral sex

Q: If a person is married and they engage in oral sex and the fluid goes in either of the spouses mouth and they swallow it does this have the same ruling like eating something haram?

Doubts regarding Hurmat-e-Musaaharah

Q: If someone touched his mother with lust when he was 10-12 years old and he is not sure about his feelings what will he do now? How could he ask forgiveness from Allah Ta'ala? What is the procedure for his Tauba? Does he have to confess. He is really upset and all time he is thinking about it and is very disturbed and in deep depression. Please guide.
