I haven't read the article yet but I will. I just wanted to get my perspective, my answer down before responding to it.
Going by only the title: I'd say without a doubt that it was bad for ME. I can't speak for other women.
I came of age in the 60's and 70's (born 1951) so I know the before and after of the sexual revolution.
As a teenager I knew for sure that I wanted children, a family, a true love, and that I would not have sex before marriage.
Then "free sex" came along and men began to expect sex from their girlfriends. I was in love with one boyfriend and he wanted sex and I said no, and he dumped me. I witnessed one after the other my closest girlfriends "giving in" to have sex with their boyfriends -- after saying no at first, but being persuaded. My very closest friend had sex for the first time in my bed with a boy who had pestered her for months, and was known as a playboy; he was 20, we were 16 and 17. I stayed outside the room while they had sex.
Later we were all in England and they were both having sex, and I wasn't. I still wanted love first. They began to tell all the boys interested in me that I was a virgin, and pestered me so long till I gave in and had sex. I was 17. It wasn't anything at all to write home about.
I do think men and boys were more respectful in the "before" era. They did not think they had a right to sex after a few dates, back then. I remember well the first time I came across that attitude - I had met an American in Bombay, hung around with him for a few hours, and then he thought he had a right to sex and got really annoyed when I said no. So all the more, I said no and didn't care about his "you frigid cow" insults.
Once you've done it though you've crossed a barrier. I had sex with lots of boys/men after the first one, and just about all of them, when I look back, I can only cringe and think what the hell. Some of them real eejits. They would mostly wear condoms.
Then, when I was 29, I got pregnant from a boyfriend I really liked. I thought he liked me too and was excited because I really wanted a baby and I was getting on in years. But he didn't. He persuaded me to have an abortion.
That broke my heart. From that day on I knew things had to change. I swore to myself that I would never again have sex unless I knew for sure that the man would welcome a child with me. Sex became almost sacred for me.
The next man I had sex with, two years later, was the man I married and had children with. We were together almost 30 years and then he dies after an illness of many years. I had not had sex for many years when he died and will never have sex again. I don't need or want it and find that I am a far more rounded, fulfilled being without it.
I know that sex is important for many women but not for me. I am lucky that I came out of that whole free sex thing with two wonderful children, now adult. I have three grandchildren. It's as if for me, the only reason I ever had sex was to have children. It's completely bound up with reproduction. And I wish I had been strong enough, when I was young, to stick with my no thanks; I think that "No" was my strength and I gave it up too soon.
So that's it; your experience may differ, but linking sex back to reproduction absolutely changed my life. Yes, I am old fashioned, but then -- I am 70 and don't give a ff what younger women think of that view. Remember I was a flowers-in-my-hair, pot-smoking, back-packing-round-the-world hippie for many years! So old-fashioned is not necessarily what you think it is.
Btw, both my kids, a boy and a girl, adopted my ideas on sexual liberation and I like what they have both become.
Sorry this was so long. Now off to read the article.
