Even I was doubtful, it was my first time taking a pill, though I had no problem getting an erection. Adds of Generic Viagra were pouring in from everywhere and I decided to capitalize on this new drug for Impotency. Somebody suggested its easily available from Shoppillrx. I ordered a 50mg pack of Generic Viagra and it has worked very well. There wasn't a noticeable difference until the 3rd dose for me. Because it allows more blood to flow into the area, there is a slight increase in size, but the orgasms are a little less intense. In any event, the stuff did a nice job of correcting my problem.I can go for a long time now before climaxing, and there is better control. Hope this helps...for a long time for me.
