You can choose between :: two ways of stimulating the prostate yourself. The first way is external - through perineum between testicles and anus. The second way is internal - through your anus. It could be quite difficult if you aren't lithe. Usually, the best position is when you are lying on your back, the knees are bended, foots are on the bed or they are pressed to your breast. In such position you can insert lubricated finger in your anus, bend it and find by feeling the prostate. Remember that fingernails should be cut shortly. In the depth of the prostate, about 3-5 cm, you will feel a small walnut sized lump on the front side of the rectum. Rub it carefully back and forth. You can also insert it and take out with different rhythm. Such movements stimulate highly sensitive nerves in anus region. If you don't want deep penetration you can stimulate only anal sphincter or perineum, it stimulates the prostate indirect. Such stimulation is much more intensive and deep. In such case it is harder to control the degree of arousal than during the stimulation of genitals. So don't hurry. Instead of the finger you can use prostate massager. It is more comfortable. Besides, all additional settings of such massagers bring real pleasure.
The other :: also well-known variant is penis rings. They are designed for men with insufficient or fast-falling erection. The ring is put on the penis at the moment of maximum erection. The penis keeps its firmness and flexibility due to thick grasp and prevention of blood outflow. Usually such kinds of erection keepers are made of latex or silicon. Can be in the form of loop. You need to begin the selection of such ring from the biggest size – rings shouldn't be thicker than it's necessary for penis firmness. Don't wear the rings longer than 30 minutes. If you like to use it longer, you need to make small pauses to restore normal blood circulation.
