I was married for twenty years. Dating when I was younger was very different, probably because of STDs (HIV and Herpes).
When I divorced and started dating again, I acted as I did when I was 18 years old. Took my time and did not push. I was in no hurry for sex because, as the article mentions, it clouds emotions and judgement.
But I found that women today are so different. My last two girlfriends initiated sex very early in the relationship. Casual sex and "friends with benefits" was unheard of when I was younger not to mention I won't even talk about what is on my phone.
I have been single for 4 years and I am still getting used to it. I'm not sure I am ever going to find a serious relationship. I am not sure I want to.
