I love the comments here. It seems that many of you believe that a woman should submit to her husband when he pesters her.
She is not his property, and any excuse she comes up with is an excuse. No means no. Perhaps the husband should clean the house or buy her flowers, make her feel appreciated, instead of being a jerk who just sees his spouse as a walking vagina?
Maybe he's already tried that and she just doesn't want sex.
I think if she said she wanted to be married and rarely have sex that she would still be single today.
I wonder if they have young children, too If so, she is probably tired from looking after them all day.
Sex is not the most important thing in a relationship.
