One drug that is being used more and more to treat erectile dysfunction is Kamagra 100mg oral jelly. When combined with sexual stimulation, its intended mechanism of action is to increase blood flow to the penis, aiding in the onset and maintenance of an erection1. Kamagra's effects can last up to four hours and usually start to take action within thirty minutes. Before taking this medication, I had an erection 40–45 minutes earlier. Kamagra oral jelly's prolonged duration was what appealed to me more than its effective benefits. It can be quite dangerous for your health to take prescription drugs without first talking to a doctor or pharmacist. The blood arteries in the penis can fill with blood when sildenafil relaxes them during sexual stimulation.
