premature ejaculation and weak erection natural cure

hi there. have you ever talked to anyone about premature ejaculation prevention? I mean, have you ever visited any doctor? it is ok that you want some natural remedies, they can be helpful. 

here are some of them. for example, they say that kava root is really helpful. this root comes in pill form and powder. it is a good thing because kava increases blood flow to the penis and slows reaction to increased sexual stimulation, therefore helping you maintain erection longer. I think that you can find it at the pharmacy store or at some health food store. also, it would be a good thing if you start to take multivitamins on the daily basis.
