Why did you have sex? I wanted to make up after a fight

Maybe you want to think about the reasons given.  Do they make sense for you ?
— learn from the mistakes of others, you can’t live long enough to make them all yourself.
Sex is a very useful way to make up after a fight.  In Song of Solomon they are very creative in using it to help resolve the fight they had.  Both were willing to make changes that would improve the relationship.  She was the one who initiated it.  The plan to use sex as part of the process of making up after a fight worked well for them.
For it to work, you need a very strong bond, and a solid commitment to each other.  Without it, eventually one or both of you will find an easier way to get sex.  You won’t have to give or ask for forgiveness.  One or both of you will be off on a new adventure, a fresh start with someone else.  At least it will look like a fresh start to the new person.  They won’t know what kind of baggage you are bringing along.

Reasons why people have sex
Most of the reasons given for having sex are from a list that Dr Cindy Meston and Dr David M Buss compiled from a survey they took.  Their list provided 232 reasons.
Compare this to the advice is Song of Solomon
She was flirting with the guy and getting turned on — Wait
She was serious about the guy and ready to make it permanent — Wait.
The guy was the one who was taking the lead in waiting.
Married, committed –Go for it and Enjoy it.
After a fight and make up sex — go for it and Supercharge it.
You will never get to Great Sex until it involves your heart, soul, mind and strength.  And until you love the other person as much as you love yourself.  All of this has to apply to the other person too.  Two people all the way into the relationship or it will never make it to great.
