Masaail relating to intimacy

Husband drinking wife's breast milk

Q:

1. Is it permissible for my husband to drink/swallow my milk intentionally and unintentionally. I am breastfeeding his son. Whilst making love to me he squeezes my breasts and sucks my nipples very hard and there is milk all round his mouth and I know he is also taking it inside.

2. Am I responsible to make food for my father in law when my husband calls me to bed to fulfil his needs and satisfy him? 

Having intimacy with one's wife while she is menstruating

Q: This is a general question but necessary all the time for those who are living abroad without their family. After long period (over 6 months). I am going for a short vacation to my home country for 5 days. During this 5 days, if my wife gets her menses, what do I need to do? Is it haram to get intimate with my wife or is it exempted, because i will not have another chance for several months thereafter.

Anal sex

Q: I am a 43 year old man. I have 4 kids. I am married for16 years. Last time, while with my wife, by mistake we entered her back side. Would it affect our nikaah? Is there any penalty for this mistake? Please guide me as I am so worried.

Husband demanding anal sex

Q: I'm starting this by saying I am married (nikaah is done but I dont live with my husband yet). I didn't know that anal sex is haram and when I found out, I started avoiding it and my husband was disappointed with me. I know I did it for Allah but he doesn't want to understand me and as well as the fact. I had read online "if your husband demands for anal sex, you can go for divorce," but I spoke to my mom and she told me that you should be doing whatever your husband says and the sin is on him, so once again I had anal sex with him thinking about what my mother said. I don't know what is right.

Also, things between me and my husband are not going well at all and I had read that if the marriage is not consummated, a woman does not have to stay iddah after talaq or kul'a.

My final questions:

1. Should I avoid anal sex and let my husband be angry with me or should I let him do whatever he wants and let the sin come on him? (There will be no point in trying to explain to him that it is haraam because he never listens to me and doesn't want to listen to whatever I say)

2. Is my marriage consummated because of only anal sex? We both have never had normal sexual intercourse.

3. Should I be staying for iddah if in case I get divorced to him?
