Question:

Hi, my name is Chris should you only take your Viagra when you know you are going to have sex? What happens if you take it and sex unfortunately doesn’t happen?

Answer:

Hi Chris,

It is recommended to take Viagra only when needed (before sex), preferably on an empty stomach or at least two hours after eating the last meal, and 1 hour before the intercourse.
It takes around 30-60 minutes for Viagra to make the effect, but this duration can be affected by food or alcohol. You should know that eating any meal before you take Viagra would cause it to make the effect more slowly. Also, fatty meals are the enemy of Viagra, they can make it harder for the medicine to reach the bloodstream.
It’s also important to know that without any type of sexual stimulation (whether visual, physical or psychological), you will not develop an erection after taking Viagra. So, if you’ve taken Viagra and don’t have sex, there is no problem and it is unlikely to have any effect on you.

I hope this answers your question.
