What is not made clear is if the good sex is with a married couple's mate or with someone else? Did I just miss that point?

We're just happy to get it any way we can.... with anybody willing....

No matter the age, people are happier period when getting laid.

Maybe for a married couple, who don't have to practice safe sex:

Now I have to wonder if this applies to absorption through oral sex?
