The answer
If the use of this instrument is for self-gratification, then it is sinful, and will alienate you from your spouse more because each one would be content to satisfy his or her own needs without the other. Sexual activity between the spouses are important for a healthy marriage. Thus, if there are issues such as erectile dysfunction in which the spouses are incapable of reaching simultaneous and mutual sexual pleasure, using this type of instrument, oils, or medicines would not be considered sinful, if the spouses are experiencing their intimacy together and striving to please each other.Answered by His Eminence Metropolitan Youssef (opens in a new tab)
