But the contemporary generation take sex as an intoxicating flashly enjoyment that causes sin which is against God.
Yes men can live without Sex but how possible is that because men love sex to the core that most of them can't even control their libido.
So, how can one controls his huge?
Man can live without anything apart from food. Man can live with clothing and shelter which are the major needs of Man. I saw someone who included sex in the compulsory needs of man. Sex it's not, whether you have sex or you do not have sex you will live. Infact when I was small I was made to believe that some people commits sacrifice that they will not have sex till they die and they will be wealthy and they keep to it.
Sex is for satisfaction and one can still get the same satisfaction that sex gives without having sex. Sex also is for reproduction and one can also produce baby without having sex. This shows that man can live without sex and man can also control his sex urge.
