I believe in love all the way and let me point out that sex is no way to prove that you love someone. Love is not selfish, dows not think about self and sacrifices for the other person. True love will only want what's best for the other person and sex is not what is best for your partner in relationship that is not marriage. True love will wait for the right time, circumstance and person.
Sex is no essential part of any premarital relationship and should not be made so. Sex has been placed at the centre of relationship nowadays which is not so. I heard a man say that "a man who claims to love you and asks you for premarital sex will be thesame man to go out for extramarital sex later."
It has been observed that mang relationships that were going on smoothly have tsken different pathways after sex. Many people have this idea that sex will make our love stronger in relationships prior to marriage but in most cases it is not so. Your respect for your partner instead sees a marked decline after sex and you begin to see them differently.
So relationships should be centred around love and not sex for any healthy relationship...
