I have read all the comments. I feel some of them are very harsh and at the same time some are balanced. You must know that India is not like the west, where even a wife can tell her husband that she is interested in swinging
You must understand the psyche of Indian women. No wife will agree with the husband right away. We all got into lifestyle the same way. She took the initiative to pen it down in the forum because it is almost anonymous and she had no one to turn to for help.
My advice to her is to not wait for the opportunity but to create one. After all, if both of you want it then why there should be any shyness / inhibition / hesitation.
Kavita, do not delay it, just go ahead and let it happen. Tell the forum when it happens and how you achieved it
