I don't think sex is wrong if the two people are mature enough and in love enough to enjoy it. It's just become corrupt in the last 30 or 40 years. People do abuse it though and confuse(afterwards) with being in love. And people also do it freely and it becomes casual and unimportant. I think there is a big difference between intimacy and the act of sex. Inimacy is wanting to share a feeling of deep love, caring, and commitment. People now, just treat it like a passtime. Like watching tv or reading a book. When sex does not have intimacy, then sex is just an act and is meaningless. But that's just my opinion.
