OK, I admit it: Every now and then, I get a little anxious when it comes to having sex. Call it temporary impotence or just performance anxiety; either way, I call it ?pretty crappy.? But it?s nice to know there are people out there who relate to my struggle. So to the folks at M.D. Science Lab, the creators of these maximum strength herbal erectile enhancement pills (now with primary nitric-oxide releasing agents!), I just want to say: ?My partner thanks you, my penis thanks you, and I thank you. You?ve made having sex just a little more stress-free.?
