Sex before MARRIAGE is a sin as affirmed by the Holy Bible. I am a man who plan for uncertainty, so sex before marriage is my desire. In addition, pregnancy before marriage is ultimately the best. God forbid - imagine NOTING HAPPEN AFTER MARRIAGE..no sexual pleasure and satisfaction, no children, wife not romantic e.t.c. I am sure I am not expected to re-marry. HENCE, TESTING/CONFIRMATION BEFORE SIGNING THE MARRIAGE CONTRACT IS INEVITABLE AND ADVISABLE.
