Nikaah & Marriage Issues

Q: I touched my mom with lust and if hurmat-e-musahara occurred, now after true tauba and promise that I will not do the sin again, can I go for Hajj with my mom?

Q: If I touched my mom with lust and hurmat-e-musaahara occurred, now I repented a lot and promise to Allah that I will never do it again.

1. Is my mom still a mahram for me, and do we still have the relationship of "son and mom" ?

2. Do I still have the relationship of "father and son" with my father?

Q: I am married for 6 years and want to have clarity on some topics which will sound disgusting but if I have clear and right information about the same I will carry on forward.

1. In Islam, is it allowed to see, rub, caress, kiss one's wifes anus after cleaning that area and making sure nothing unhygienic is there.

2. Since anal sex is haraam, can I massage/rub with my finger on my wifes anus. I wont be doing any penetration with hand/penis.

3. Can I have sex with my wife in the bathroom and kitchen or any other place in my home.

Q: I touched my uncle's wife (mami) with lust when I was 16 or 17 years old. I imagined her while doing a bad thing. I also touched my private part to hers when she was sleeping and kissed her but she didn't noticed. I am very shamefull and regret that.

Now I want to marry my uncle's daughter (mami's daughter). Can I marry her?

Q: If a persons wife is uncomfortable in providing her husband with some of his rights, can the husband leave those rights with his own will without any pressure?

If he does so, by his own will and happiness, is the wife still committing a sin?

Q: A girl is 16 years old and she got married to a 27 year old boy knowing that the boy was having an affair with her own aunty (girls mothers real sister). After one month of that girls marriage, her husband got married to her aunty. 

So my question is... is the first marriage halaal or haraam. If it is haraam then can the girl get married to another man without any divorce or khula?

Q: Is my husband a mahram to my grandmother or should she make parda from him?

Q: With consent from my parents and siblings, and my husbands entire family (but not his father), I had my Nikkah in November last year. As soon as we announced to my father in law, he was over the moon and incredibly happy. Some realtives also knew about the nikaah beforehand as they arranged our marriage. The Nikaah was beautifully done at the mosque in front of witnesses and my mother and sister. After the Nikaah my parents announced it to other relatives and friends. I and my family received a lot of backlash.

My question is, Islamically did we do any wrong in keeping the nikaah discreet from noise and simplifying it as best as we could? I have received love from my in-laws and family members who were generally happy. Some relatives and family members may forever hold a grudge of some sort. For my own contentment, I wanted to ask if I did anything wrong or were there any mistakes in hiding it from certain family members?

Q: When my son has his own job and he is earning then is he dependent on his father?
