Is it permissible for me to ask my husband to use a condom to prevent diseases if he marries another woman?

Adultery is one of the gravest sins and has severe consequences in this world and the hereafter. A wife is not entitled to demand the use of contraception unless there is a reason, such as her husband having a sexually transmitted disease or being involved in an illicit relationship. In such a case, she has the right to demand it to prevent harm, or even to seek annulment of the marriage if the disease is serious and incurable.
