Generally, it is the woman who has low sexual interest but the dynamics are the same. I know you cannot make a man have sex. A woman can be submissive, a man cannot. An erection is necessary for intercourse and for a man to be even semi aroused, he has to be interested. Very likely the lack of sex in your marriage does not mean there is not love.
Some people have no interest in sex other than to make children.
Needs must be met. Compromises will need to be implemented if the relationship survives. Good luck to you both.
