Answers: What are the effects of it?
Viagra is to help a man perform his work in bed with a woman or a man, it's effects are to let you have a hard on for as long as you'd like to have sex with the person you love or like, but there are other web-sites you can go on to find out more about your question, some people go to www.ask.com and ask their questions but I say that you needed a desperate answer.
