To keep it really hard and completely satisfy my wife, I would have to thrust faster, which would cause me to orgasm, ejaculate, and lose my erection - sometimes before my wife was ready. I tried a sample of 50 mg viagra when I was 52. In 20 minutes, I felt a little flushing. When I went to urinate, my penis started getting erect just from me touching it. I showed it to my wife, and she said "let's try it". As we began foreplay, my penis became very stiff and full. My erection stayed through a half hour of foreplay, and after penetration, it stayed hard, reaching up to where my wife always enjoyed it. I was able to pace my thrusting to my wife's journey to orgasm. I decided to keep going slow so she could orgasm longer. All the while, my erection stayed at maximum. Finally, I orgasmed and ejaculated. Having waited longer, the orgasm was strong and the ejaculation had a lot of force and volume, which doesn't always happen with a "quickie". I noticed my penis was still very hard after orgasm, and I kept thrusting, along with my wife. With the head of my penis still reaching up and rubbing on her uterus, I orgasmed again, as she continued to do so. This wasn't my first double orgasm, but it sure was the easiest. Then my erection subsided, more slowly than normal. Since then, I have cut 100 mg pills into quarters, for 25 mg. Works just as good for me. My erection stays good and hard until we are finished.
