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.

Marrying someone who is 15 years older

Q: I am writing in regards to a marriage proposal. I have met someone I like and he likes me and we want to get married, however we have a 15 year age difference. I am happy to go ahead and marry him and feel very positive about his character and personality and feel that we are similar in terms of maturity and mindset because I have always been mature for my age due to being the eldest child and not having a father growing up. My family like the guy and have no issues with him but are just a little worried about the age and if it will cause problems in the future. What should I do because I really want to marry him and him me because I feel that everything else is perfect for me and I like him and his character and deen and his family and his family have many age gap marriages from 10-18 years age gap and they are happy masha'allah so they have seen it work and are ok with it but my family are a little hesitant but they do really like him and his deen and character and said they have no problems with him otherwise. I would appreciate your advice on the matter. Jazakallah khair
