Viagra

Hi ladies! So my husband has some trouble staying hard. He can get hard and stays hard in the beginning but after a few minutes he goes a little soft. Not completely soft but not “hard.” He tried an off brand of viagra called Fildena and it worked amazing! I am trying to convince him to go to the doctor for an actual prescription but he doesn’t want to. Do any of you ladies have experience with this? Does any one know of a way to get viagra or an off brand online? I am too scared to buy from an unknown website, I heard there are a lot of pharmacy scams online.
