It is not unusual for couples to use sex toys to add a little spice to their sex life. We are often looking for a new thrill to switch up the normal routine and the penis ring is a common choice to change things up. Furthermore, a penis ring will slow the flow of blood towards an erect penis. This helps men maintain an erection for a longer period of time. Men who have issues maintaining an erection should consider using a penis ring to both add a little flair and increase their length of sexual activity.
