Good stuff guys. Stardust i suspect you're not going to even consider my advice but here goes. She should ask her husband what will it take for him to stop watching porn. She should tell him that the thought of him comparing her to other women saddens her. She can also ask him how would he feel if she watched porn. She should tell him that even though she is satisfied with their sex life, how would he feel if he ever caught her looking at a 'huge' man? Wouldn't he feel inadequate? Finally she should say that if he really wants to watch porn, watch something that they can watch together. 'cause no desi would wanna watch porn with his wife.
In the end you'd have a much happier wife.
I will take on your advice because it is constructive and much appreciated.
