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. Ability to get that kind of erection remains for at least the next 12 hours. Also, when my wife isn't available, I occasionally use viagra to get an erection I can really enjoy for masturbation. Not necessary, but fun for sure. Only change from experience above is I now take Flomax, which decreases the volume of my ejaculation. Also tried Silagra from Cipla in India. Works at least as good as Viagra. imiquimod order shopping australia
