Will a wife who is not asked by her husband to bed and he sleeps be held accountable, and does the husband have the right to hold her accountable?

It is obligatory for the wife to answer her husband if he calls her for intimacy, unless she has an excuse. If the husband does not ask, she is not obligated to offer herself to him. However, as part of good companionship, she should consider her husband's circumstances and not be preoccupied from him. She should also beautify and adorn herself for him to keep him chaste and to gain his affection. She will be rewarded for this.
