Hell just go see your doctor and tell him you are having trouble with performance. Ask for the 100mg Viagra. I get 20/month for only $11. Use the GoodRx coupon at your local Kroger. They work like a charm. You can beat the brakes off a chick all night. They only drawback for me personally is that I don't ejaculate if I take one. No biggie to me as long as the lady is having countless orgasms
