Marriage is a religious tool and government business contract designed to put money into the court coffers. Don't believe it? Go through a contentious divorce. With a JW. If you marry someone without having lots of sex with them you are a complete idiot. Why not have lots of sex, make a commitment to each other in your heart if inclined, enjoy it while it lasts?
Probably not one of my more benevolent posts, but marriage and abstinence is completely overrated.
