I’m fond of viagra

Good day! My name is Dmitriy, I’m 58 years old. I have to use several drugs as I have diabetes and high blood pressure that caused problems with erection as result. When I visited my doctor he told me that i should try Viagra. He prescribed me 50 mg of viagra and said that I should start with half of pill, with 25 mg. After taking a half of pill I was very suprised. My penis became> very hard and I had an erection that lasted for about 30 minutes before I got the orgazm.
After short rest for 10 minutes i had erection again! I’m very happy as i get stable erection during sexual arousal even after several hours after using of Viagra.
