What should couples do if they feel that they are completing their tasks because they have no passion in sexual life?

This is a cold phenomenon caused by ignorance of skills, or it may be that the man's time is not good, which leads to the woman's indifference and no feelings. You can use some jumping eggs, vibrators, oral aphrodisiacs or external spray to prolong men's time. Don't be shy, your sexual happiness is the most important thing.
