I have grown up in western Europe where we have a completely different morality than in the US regarding premarital sex. It is quite common to have sexual relationships from sixteen years on since the 70ties. Of course sex between eleven year old kids is horrible BS. We Europeans have such weird problems too, especially among the lower class. Nevertheless - from my point of view it absolutely not common to start such contacts before being at least 15 years old on our side of the big pond. Our kids are well advised in the use of contraceptives and to my knowledge we have much less teenage pregnancies and generally lower AIDS-rates than in America.
Therefore I have to say that my personal experience was rather the other way around to what you were saying. Since girls are usually a littlebit faster in their general development they turned us guys into the objects of their obsession or turned to boys who were old enough to keep up with their needs. It was not me that seduced, I was seduced. Nevertheless my male ego (which is probably quite developed) never suffered from that and I do not want to miss this adventure. Women and girls who know what they want and who do what they need are usually much more interesting to us men than those who do not.
I am well aware that such behavior is a religious problem. Furthermore sexual activity opens more of ourselves than anything else we are doing with our partners. It makes us extremely vulnerable. Therefore I think everyone has to decide on its very own whether he/she wants to start a premarital sexual relationship or not when he/she reaches the maturity to do so.
BTW - My own premarital experience never took the ability to build up stable relationships from me. I am a happy and faithful husband since 11 years and I am the father of 3 great kids although I had quite a few girlfriends when I was a young guy. This would be probably not the case if we Europeans could not act freely as young people. If I would have been forced to marry my first girlfriend to satisfy my physical needs (that are simply present from a certain age on) I would be a really unlucky man today. Thank God I am not.

Yeap! There it is! That pesky religion. Definitely a “ problem”! (sarc 0ff)
