I know gay men who are very happy with their wives but still need the fulfillment of a male sexually. They hold out as long as possible, but eventually give in. Most women who marry gay men are wonderful women. They always try harder in their marriage because they sense something is wrong and they personalize it. They think that the problems in the marriage are because of them, when in fact, it has nothing to do with them.
Most husbands only confess once they get caught.
Many never tell the truth. It is too painful for them to have to admit to themselves that they are gay. Gay is not a choice. No one would choose to be gay if he didn't have to. That doesn't make us feel better, but it should be a comfort to know that we have no responsibility in this situation.
