Viagra really is too damn expensive. But, as far as I know, this is the only reason people should avoid it. My husband use sex "boosters" from time to time, because he has ED for about 2 years now. And he's ok.
Does it really requires for People with ED?
Well anyway I am lucky because i never come to use any of these kind of Pills or boosters because My Sex life is pretty colorful even we have been married for more than 2 decades now.
