Viagra may allow you to remain hard enough to continue sex after ejaculating, but it doesn't treat premature ejaculation. There is a drug called Priligy (brand name) that is supposed to do this. It's available in the Uk, but I'm not sure approximately other countries.
Ask your gp there are all sort of medications to help out, there are also help. It's not an unusual situation so just enjoy.
There is a pill called Super Kamagra, or Super P-Force, which contains Sildenafil Citrate (the drug that helps Erectile Dysfunction) AND Dapoxetine (the drug that helps Premature Ejaculation). You can buy it from Exact Pharma @ http://www.exact-pharma.com
