it all depends on whether u r young or old, and aroused enogh or not when u have sex with her.
if u r old and not aroused enogh to have sex with her, then it might not be such a strange problem. just try Viagra(over dose at one time can be deadly, so be careful)
however, if u r young, like teens, and aroused enough, then it is a problem, a quite big problem. seriousely, go to ur doctor and get some advice.
