They probably thought it would be a pattern with you ;)... No sex unless you keep giving her whatever she wants.
Sex before marriage is wrong.
And risky.
To many women have been burned by giving in and then shortly after having the guy dump them.
They know they were just another conquest for him.
Men want pure women and then when someone comes along with a *no ring, no sex* policy, she's criticized for using sex as a weapon.
Goes to show that you can't please men.
