After using a sexual performance medication, worry, stress, overuse of the medication, exhaustion, alcohol, or the tablet's negative effects may cause temporary difficulties getting an erection or ejaculating. A single incident does not always indicate long-term harm, and many men are able to resume regular sexual activity with enough recuperation and self-assurance. Because the precise ingredient and safety of medications like "Juan 50" are unknown, do not continue taking them without a doctor's advise. Performance may naturally improve with regular exercise, restful sleep, less stress, and abstaining from alcohol and tobacco. See a urologist or sex expert for an appropriate assessment and safe therapy if erection or ejaculation issues persist.
