My wife and I were religious when we were dating and engaged. We did not have sex before marriage with each other. We are coming up on 20 years of marriage in December. I would estimate that we have sex between 1-4 times/week. There are some times that we go 1.5 weeks between, but it's rare and just kind of happens. But we talk about frequency and what kind of life we want to live directly. Having less sex is a choice for most, but not all, of people. You can choose to continue to have an active sex life. As an example, I prefer to go to bed early, she prefers to go to bed late. As a result, we often tend to have sex on weekend mornings (our kids are older and sleep in). That works for us. We probably have 50% night time sex and 50% morning sex.

I will also say, through lots of communication our sex is light years better now at 20 years of marriage than when we were first married. Our emotional connection is incredibly strong, and we have 20 years of communication to make the physical sex better as well. I am much happier sexually in my 40s with my committed spouse than I was as a teenager having sex (before I was religious) with different partners (the "variety" that the article mentions). Don't lose hope people. You can make a great life after marriage that is deep and rewarding sexually. Marriage can be wonderful if you value the right things in a partner and find that partner.

Over 60%[1] of these couples have sex more than once a month, and 46% at least weekly. So, hmmm, where are you getting your data from? I guess if you compare to when you first meet vs. 20 years of marriage, the amount "has gone down" (daily vs. weekly now), but that's probably more than I'd get being single at this age.

Even if it decreases when measuring in weekly or monthly terms, in all likelihood if you're measuring in terms of years and decades, a married person will be doing better than single folks.

Don't forget to tip your waitress, folks.

Not if you waited until marriage.
