Ok here is the deal. I am soon to be 49 and have noticed that my sexual stamina has started to decrease. My dick does not get real hard anymore and it makes it difficult to penetrate my partner. I know that viagara will give you an erection, but does it make you cum more? Is there something over the counter or by rx that will enhance my sexual desire. I have always had a real active drive and want to continue it and am not to embarressed to ask for help. Any suggestions from anyone will really be appreciated.
