The inability of men to get hard during sex is often a manifestation of impotence, especially in adolescent males who are overly nervous during their first sexual encounter or due to the lack of cooperation from their sexual partners, which usually results in the occurrence of an erection. To treat this, the patient has to engage in adequate sexual stimulation, that is, to enlist the cooperation of the sexual partner, to fully engage in the process of sexual life, by improving the method of sexual stimulation thus promoting the erection of the penis. If the penis is still unable to erect, you can take some drugs orally to relieve the symptoms, such as the commonly used Viagra, cialis, etc., orally before sex, during sex by fully stimulating the penis to promote erection, so as to achieve a satisfactory sexual life time. Be careful not to be overly nervous in order to reduce the probability of impotence.
