What do you do if your husband does not give you your right in bed, and he invalidates your ablution, and what results from that is the interruption of prayer and scarcity of water?

It is part of conjugal kindness for the husband to ensure his wife's chastity and enable her to satisfy her needs, and he must not hasten to finish until she has fulfilled her desire. The wife, on the other hand, must respond to her husband's call to bed whenever he requests, unless it distracts her from obligatory duties, harms her, or prevents her from prayer. If the wife does not find water after ritual impurity (janabah (definition)), she must perform tayammum (definition) (dry ablution) for prayer, and she is not permitted to delay it past its prescribed time.
