How often can you keep the erection after penetration during a coitus?

Was it difficult to you to keep the erection to the end of coitus?

How often were you satisfied with the coitus?

If you have 21 point and less, it means you have some sexual dysfunction and should consult a doctor (andrologist, urologist) and probably try to use the electrical pulse stimulator Erectonus.
