Is a woman permitted to refuse her husband in bed sometimes, given that he has frequent intercourse and she is bothered by that?

The hadith indicates the impermissibility of a wife refusing her husband's bed without a valid religious excuse. Therefore, it is obligatory to obey the husband and fulfill his desire for intercourse, and it is not permissible to refuse merely due to embarrassment or discomfort, or due to frequent or repeated intercourse, as long as the matter does not reach an unbearable hardship that is not customary. If the refusal of intercourse occurs without significant hardship, it is considered an act of defiance (nushooz) and a sin.
