For man, KB controls sex, your good sex depends on your strong KB system.
For woman, LG controls sex, your good sex depends on your strong LG system.
Correct sex will make you happy and healthy, over sex will possibly make you happy but will make you sick.
Over sex will consume your KB or LG energy to make you weak. With over sex, you will feel that ears start ringing, hair loss more and more, waist starts dull pain, bones start dull pain, knees start dull pain, memory starts loss, sex ability starts going lower and lower etc., your confidence starts losing which you are not aware of, because KB system is connected with your confidence, memory, waist, bones, bone marrow, spine, spine marrow, brain, ears, hair, knees.
If you couple get orgasm at the same time, it will replenish your energy. To reach orgasm together at the same time, it needs you couple respect each other, take care of each other, it needs you have your self mind property to show selfless and then you couple can win together; if you follow educated mind property, you only take care of yourself, never consider your partner, you yourself possibly win happiness but you will lose energy and your body will become weaker and weaker day by day. So you are selfish, you will lose, you are selfless, you will win. This rule is applicable for not sex but everything as well.
You should follow sex frequency below to keep your energy:
3 times per week: <30 years old
2 times per week: <40 years old
1 time per week: <50 years old
2 times per month: <70 years old
1 time per month: ≥70 years old
If you do over frequency, you will get energy lost, and your body will get weaker and weaker day by day, and your KB system problems will happen day by day as above.
