You are a young person endowed with good amount of energy. Why do you want to take such powerful erection drugs (unless of course if you have health conditions like long-standing
diabetes, high BP etc)? You could have considered ayurvedic supplements instead. Majority of them do not cause side effects. They may be slow to act but safe and good in the long run.
Good lifestyle, relaxed mind, regular workouts, and sex knowledge will keep sexologists away! 😊
