I have NEVER met a single woman don't say that they lost their time after a relationship came to an end. With that being said, why women have sex BEFORE marriage? Taking away the 'Christianity' factor, please, hear me out. Sex is valuable. Virginity IS valuable. If it wasn't, there were not virginities being sold out there for millions. If sex was not valuable, you wouldn't have a whole prostitution industry. With that being said, before premarital sex was a thing, women married the man, who would give half of his life and assets for her in exchange for sex and for some menial stuff, like home cleaning and food. And he would have to pay a VERY high price if he wanted to go away. She had the whole Law by her side. Now, we have 18, 19 year old women exchange sex for pizza, a hand holding and some "validation" by her "friends", who don't pay her bills. Now, the man, after years of relationship, can cheat and leave, and he won't have to do NOTHING. And the woman will be left with a broken heart, wasted time, and pray that not, a baby. Don't say this doesn't happen. I've seen it plenty of times. Single motherhood is at an all times high, and, before you mention it, child support DOES NOT cover the whole of bills, at least not outside the US, and single mothers are, more often than not, miserable, financial and psychologically. I have seen it with my own eyes girls carrying relationships throughout the whole graduation and the boyfriend just leaves because he is done with her. So, I ask: WHAT a woman gets if she gives herself for a man but does not demand "the ring"? A "relationship" is not a legal agreement, and, after days, he can leave her.
