I cant believe you use this as a litmus test to whether you are marriage material or not. It's near talibanish/7th century way to marriage.
Just the opposite, this is a personal realization, not a dictat from anyone in authority. There are a goodly number of people out there who, one way or another, decide that they are just not inclined to marriage, or even dating. Many are not particularly even interested in sex.
This is pretty astonishing to those whose lives are truly defined by their sexuality, or at least by their sexual relationships. They cannot imagine how or why anyone would be like that.
It worked with my wife.
