Is it true that men can't stay in sexless relationship?

Men, generally, don't want to be in a relationship that's doomed to have no sex. For the men that do, it's likely because the relationship somehow slipped to that and they are now trapped out of commitment. This is one of the reasons some men resist the idea of marriage. Factors like conversations, empathy and understanding come first in a relationship, but it doesn't mean it's fine to refuse an intimate physical and emotional need.

A sexless marriage is not a happy or healthy one, no matter what people say while trying to break traditional expectations in a marriage. It would be much better and practical to be friends with the person of the opposite sex, if you don't want to have sex, but couple have no clear foresight. There's no guarantee that the marriage is going to continue being sexually satisfying, though I don't think that's the case with most marriages.

There are some categories of men that can live in a sexless marriage, though they usually have special circumstances, being asexual, impotent and other physical reasons. The reasons also happens with females, but it's more common with males.

There are some men who are asexual which means that they can stay in the relationship for a long time without having sex. There are some men who can stay in a relationship for a few months while there are also others who would not be able to do it. It would still depend on the man and how much the man respects the woman.

If he cannot do it, if he cannot stay faithful to the woman because the relationship is sexless, then he would eventually leave. It should be remembered that a relationship would require intimacy. It does not require sex all the time but if couples cannot be intimate with each other, this might signify that the relationship is in trouble.
