Men have their reasons to reject such things. It may be a Body Odor , body shape, emotional reasons, stress of many kinds. Most men have a hard time to express such problems to not to offen the other person, but they do without realizing. Stephen Covey who wrote my all time favorite book 7 Habits of Effective People says, "First seek to understand in order to be understood." The reason may not be what you think it is. Maybe it is you, maybe not. Maybe it is some deeper cause.
