Viagra abuse may increase the risk of contracting HIV or STD's during sex or cause other health problems.
Viagra, manufactured by pharmaceutical company Pfizer, increases blood flow to the penis
. This prolonged rise in blood circulation can increase the risk of transmitting or contracting HIV or blood borne STD's, especially during oral sex
if either partner has a cut or scrape in the gums or during anal
if there are abrasions.
