I am really interested to know if there are any legitimate, Male Enhancement/Libido raising/ supplements on the market?? There are literally thousands of them I noticed, and I imagine most are worthless and a waste of money .I am a 70 year old man, pretty healthy. I also had a urologist check me out recently, and was told my testosterone levels were pretty good for my age ,and that my prostate was SLIGHTLY enlarged, but nothing of concern right now. So I don`t know what the problem is . I have very low desire, ,but use Viagra or Cialis for help to get and maintain an erection. They DO work , when I use them, but the " horniness or desire" is actually not there normally until my wife initiates intimacy, and slowly coaxes me to take a pill, and then gets me to the point of erection after a while. We would BOTH like to have a more active sex life............. it`s come down to maybe once a a month....IF lucky. All her doing BTW. Am really frustrated ............please help ??
