love/sex between a consenting adult man and woman...boyfriend/girlfriend even though not married ...is perfectly alright and it is not going to doom the universe.
any one who thinks marriage is a license for having sex is a fool of his own making.
Sex education, Sex before marriage should not be viewed as taboo's ....also living together before marriage should be encouraged.
why waste your life in getting married to some one ...you do not know if you can have a screamingly ecstatic orgasm
arranged marriages should be discouraged because they result in extra marital affairs ...due to in compatibility between couple and couple are afraid they will become social outcast if they divorce.
In US I have seen tons of couples living together for more than 5 years before getting married....and it doesn't seem to have done any damage to earths location in universe.
so stop this cultural shit and let people live their choice of life.
