Perhaps I was too oblique.
Pre-marital sex isn't a mistake. It is, often, a useful tool in building a long term relationship, it can go a long way in teaching people to be emotionally involved with others in a healthy way, and is often very useful in learning to deal with the flood of hormones and emotions that late teen/early 20's years bring to humans.
Like many other useful, healthy behaviors, there are risks, and can be consequences that should be fully understood, and considered before engaging in that activity. The fact that negative outcomes can exist doesn't mean that the positive effects aren't there, or shouldn't be pursued.
You are wrong on this subject, and too poorly educated on it to realize it. Which is kinda sad.
Speaking solely for myself, I had sex with a number of young ladies before marriage, don't regret any of the relationships, and am still friends with a couple of them. That behavior takes nothing away from the intimacy and love of my marriage. The very idea of treating relationships I had with young women while we were both still growing up and finding out who we wanted to be as mistakes is insulting. Both to me, and to the ladies, whom you don't know, who shared intimate parts of their growing up with me. The arrogance of such is amazing.
When that arrogance is coupled with the smug religious overtones that you (knowingly or not) imbue in most of APS's discussions of a sexual nature it takes on an even more insulting nature.
I'm not actually upset with you, even while being insulted, because there's no real point. My point of view effectively won the culture war on this topic decades ago. I'm simply pointing out to you how rude and insulting you are being. Many of your posts make it seem like you don't really realize how you're coming across to people who might not share your experiences or point of view. I also think you tend to conflict correlation and causation among any issues, or societal ills, associated with sexuality.
