The basic purpose of Viagra (sildenafil) is to treat erectile dysfunction by boosting blood flow to the penis, which facilitates the development and maintenance of an erection. Although it has no direct effect on how long a sexual encounter lasts, some men claim to have more stamina than before.
This is frequently because of the enhanced erectile function, which enables longer and more reliable sexual performance. Sexual endurance in general and problems with early ejaculation may not be resolved by Viagra alone. Changes in lifestyle, pelvic floor exercises, and partner communication can all help ease worries about spending more time in bed. It is important to speak with a healthcare provider to determine the best course of action for each individual's needs, since medication alone might not be able to address every facet of sexual performance.
