I am 35-year-old married person. Now a days I am attracted towards a woman, is my very close relative @ 42 years old. I have a very strong will to have a sex with her, but I’m confused how to ask her & complete the matter with having at least once a sex with her, whether she will agree or not.

There is nothing new about having desire to have a sex out side marital relationship. Many males will have this. However, any sensible and decent woman will never be interested in having sex like the one you want. You want to complete the matter?! It gives me a feeling that you are seeing her as a sex object and have no emotional bond. This is certainly not a healthy thinking. Try to get over your will and stop dreaming to fulfill it the way you want.
