Comparison of the effects of different erection drugs in prolonging sexual activity time?

The effects of different erection drugs on prolonging sexual activity time also vary. Some drugs, such as tadalafil (Cialis ), have a longer duration of efficacy, up to 36 hours, making them suitable for men who wish to maintain their erection ability for a longer period of time. However, other drugs such as sildenafil (Viagra) have a shorter duration of efficacy and are suitable for one-time activities.
