It should be clear that both the husband and wifeshould satisfy each other in bed.
If one of them fails to achieve this marital duty, he/she should resort to medical treatment or Islamic professional counseling.
The Qur’anic verse states that “Whoever seeks satisfaction beyond marriage is among the transgressors.” (Al-Mu’minum 23:7)
We should earnestly try to stay within theboundaries of marriage. If the husband cannot satisfy his wife, then both of them should seek medical treatment because there might be a certain reason that can be treated.
After doing this, if the problem persists, and there is a necessity to resort to these tools to seek sexual gratification, then the husband can use those tools to satisfy his wife. The reason for doing this is to keep sexual gratification within the boundaries of the husband-wife relation.
