You should take Cenforce 100Mg on an empty stomach at least 30 minutes before sex. It takes effect around 60 minutes. It works by stimulating blood circulation in the penis and relaxing the smooth muscles. This action causes the penis to absorb maximal amounts of blood. This results in an erection, which is the maximum absorption of blood by the penis. It is a natural process, and you should not worry about how long it takes to develop an erection.
