Welcome to HCM
You are 45 and otherwise healthy male. You had habit of intercourse with males in younger age. You have three children. You can't do intercourse more than 5 seconds. You are taking 200 mg viagra per day. You also had operation of hernia 7 years back.
First of all I would like to tell you that operation of hernia has nothing to do with this problem. I would advise you to quit smoking
. Smoking may increase this problem.
The problem you are having seems to be premature ejeculation. You are ejeculating before desired time. Viagra help in getting erection but it don't help to increase the time. Various medicines can be used in such cases like Dapoxetine
which is a SSRI drug and which should be taken 2 hours before sex. It increases the time of intercourse and it delays ejeculation. But for medicines visit a good Psychiatrist
Also get your blood sugar levels and Blood Pressure checked. Diabetes
may be the reason behind these problems.
