It's really not a matter of my being either for or against premarital sex that in question.
Pre marital sex meaning sex before marriage.
The last thing a marriage should be based on, is sex.There are lots of valid reasons to marry; sex shouldn't be one of them.
It's certainly not neccessary to be married to have sex and it shouldn't be.
Sex like hunger is a natural born instinct and should be treated like it is, not regulated by religious beliefs that niether God or Jesus dictatored. They're all add on's writen by men who thought the earth was flat.
The real question here is why are there rules governing consensual sex in the first place.
Why is it that everybody is so willing and so easily lead into what and how to think about our most basic instincts by simply saying," God said", or "Jesus said," or "they said," how or what you should think.
What the hell is wrong with all of us.And,..
in your question you ask, "why did you (I) allow it".
Who in the hell am I to be allowing or dis-allowing some one else's sexuality. I may be able to advise or possibly even help educate some, you know, about safe sex and all.
About the responsibilities that sex can and does bring.
All things that should be available to young people as soon as they start asking or showing interest.
If responsible people don't do it, someone else who may not know their anus from a hole in the ground certainly will. Someone who may very well have an agenda of their own.
