My virgin for my love is wrong way

my virgin for my love?stoooopppp,it's wrong way,why sex before marriage is wrong why?in the bussines,we make transaction with some one that we knowladge,it's simple thinking,but how a bout sex before merriage?the first anwers is merriade with your lovely,merriage is onus shape and real shape from love.so it/s like we make transaction with some one that we knowladge
the second anwers is we are human being and perfect creature in the world,we defferent with animal,so we must merriage for make love with our lovely to discriminate human or animal. ( Thanks )
