Ref. No. 1124/42-348
In the name of Allah the most Gracious the most Merciful
The answer to your question is as follows:
Physical contact requires sexual arousal. Hence the husband has the choice to reduce physical contact with her, and in this regard he cannot be forced. However, it is mandatory for a husband to maintain equality with all his wives meeting all requisites of their life and spending nights not necessarily having physical relationship. Sometimes physical contact with the wife and the fulfillment of her sexual desire is obligatory upon her husband in accordance with the Islamic conscience.
یجب ان یعدل ان لا یجور فیہ ای فی القسم بالتسویۃ فی البیتوتۃ وفی الملبوس والماکول والصحبۃ لا فی المجامعۃ کالمحبۃ بل یستحب ویسقط حقھا بمرۃ ویجب دیانۃ احیانا۔ (ردالمحتار 4/378)
