When you become interested in sex, your penis should quickly or later erect. Once erect, you can have satisfactory sexual activity, indicating that sexual function is not a major problem.
Secondly, looking at one's own physiological and psychological reactions to sex, men with normal sexual life and sexual psychology will have imagination when they see young and beautiful women, and when they see their wife's naked body, they can't help but want to touch it.
Take a look at the initiative of sexual activity. If you initiate sexual activity every time, it indicates that your sexual function is normal. It is normal for you to respond positively when your wife initiates the incident.
If it is always initiated by your wife, otherwise you will not be interested in sex, which indicates that there is a minor issue with your sexual function. If one is not 'moved' even under the guidance of their wife, there is a big problem.
In the above situation, if no sexual imagination is generated, it indicates that one's sexual function has started to become dull.
Through the above "three looks" self test, if one's sexual function is within the normal range, there is no need to worry about temporary "weakness". If it is abnormal, one should seek medical treatment as soon as possible.
