let me join you...just two things to highlight...medical research and talks from the grapevine...

erectile dysfunction is usually associated with poor circulation of the blood. during ***ual excitement, the central nervous system sends impulses to the oxygen carrying heme to rush through the man's penis. in a way, viagra enhances circulation but it does not necessarily follow that the man taking this attains the desired erection...so if a man is capable of getting excited during foreplay, taking viagra is an overkill. on the contrary, a man taking viagra may still fail to maintain an erection. why? because there never is a ***ual excitement...that's why in law, relative impotency is recognized.

from the grapevine:

i am out of town and on leave...my attention was called coz a kababayan was found dead in a motel...the grapevine has it that an empty pack of viagra was found in the trash can. twas only 3 days after his death that he was discovered and in a decomposing state already...yet the little citizen still pays respect to the flag...

this is a case of overkill...he was capable of ***ual excitement and unnecessarily reinforcing the same with viagra...the grapevine has it too that he prostituted a woman, who fled when he suffered a cardiovascular attack. here, the blood rushed to the heart and not to the penis.

RIP

it's only this time that i fully appreciated what my medical jurisprudence subject has taught us in connection to legally putting an end to a marriage by reason of relative impotency...that is, a man may be declared impotent even if some time in the past he impregnated a woman not his wife.
