Any erectile dysfunction should be consulted with a doctor and sexologist. Excessive use of Viagra (and other preparations containing Sildenafil) may lead to problems of "psychological dependence", but it is worth excluding health problems that may cause erectile dysfunction. "Psychological dependence" is not the same as actual addiction, because the active substance contained in the drug does not exert such an effect on the body. The problem concerns the psychological aspect - often stress associated with the risk of unsuccessful intercourse. Transient erectile dysfunction may also be associated with frequent and prolonged erection (as a result of the drug used) and sexual exhaustion. In this situation, it is worth giving the body time to rest and regenerate. I encourage you to visit these specialists if the problem persists for a long time.
