What do you get out of this advice?
A whole bunch of nothing. Every situation, every relationship is different and should be treated as such.
Are you bothered?
Yes. The article makes a lot of assumptions I disagree with. It suggests that sex should be used as a manipulative tool, versus as something to be enjoyed between two people.
Do you benefit from it?
No. I slept with my SO on our first real date. We've been together over three years. I don't think Mr. Harvey's advice is relevant to me in the slightest, and I think other women should take it with a grain of salt.
Do you find that it plays up to stereotypes?
Yes, especially the idea that women enjoy sex less than men. It's complete bullshit.
Do you think something entirely different?
Obviously!

In my experience, there were definitely times where waiting was prudent, and there were times where it was clear that waiting was a waste. When I met my SO, I just
knew that what we had was very, very different than any other relationship I'd been in, and I didn't see the point in holding off on something we both wanted.
