1) You need to be circumcised first to increase your durability
I'm not familiar with this. How does being circumcised increase durability?
2) You need to conduct a healthy way of life to increase your stability
As in Celibate periods. But, how do you get your wife to consent to this, and still allow for her to understand, that you really are interested in her and do still love her.
3) You need to conduct a modest way of life to increase your wife’s excitement while in private. For example, a couple that sees each other naked all the time will have a hard time getting excited.
Certainly. I can understand this. But, again as above, how would a husband, deny sex to his wife for a day, two days or a week, in a loving way. It is hard for me to picture myself saying, "No!" It would be ideal if she could understand the reason for the, "No!" How to make her understand without a long lecture.
