That is a question that Lori was asking and I thought I would give my two cents. Without trying to be cute, I think the better question is what makes love good. If its just about sex, buy a book, figure out what your partner likes, and practice as often as you can or insert she wants 
But that isn’t what makes sex good.
Love is what makes sex good.
A love that says out of anyone on the planet, I choose you for my life.
A love that says I will respect your comfort zones.
A love that says you don’t have to jump through hoops for me to appreciate you.
A love that says we won’t use sex as a power or pressure point in our relationship.
A love that says sex won’t become a tug of war game for us.
Sex is great, but love is the good stuff.
Work on your relationship and great sex will follow.
Work only on your sex life, and well, you may have pleasure but can lack promise.
What makes good sex?
You fully loving the person you are with in every way, including sexually.
Nothing more, nothing less.
“Work only on your sex life, and well, you may have pleasure but can lack promise.”
That’s a good word if ever there was one.
Love it!
my pounds of The Fear Of God, to the obedience of his commandments, when the people of God chooses to talk to others about theirprivate lives in public, isn,t it written blessed are those who confide in The Lord Who,s New Name is The Word Of God as written in the book of revelation 19 and cursed are those who confide in men, and if you sin tell a true brethren that if the sin may be forgiven that one may pray for another, the dearly beloved Paul who has his white stone as i do, suffered all the hardship that all that one needs for prayer before The Lord is! this not many did suffer as him, and it was for the edifying of the saints that they need to ask no one how to manage their homes
