this is a real side effect for some men. it rather dramatically changes my flacid state (gets smaller).
i don't know why some people have trouble understanding that this can be an issue for some. this medicine toys with all things related to sexual chemistry.
my guess is that it has something to do with the fact that a good portion of the penis is inside the body, near the prostate. if that reduces size, the whole region may pull back inside somewhat.
my guess anyways, but ya, for you skeptics out there, this is real.
