Helping a friend

Julia

So my boyfriend's friend has a problem with getting hard. He really likes his girlfriend and doesn't want to make her feel insecure but he can't get hard unless he himself strokes it, and even then it doesn't stay hard. I suggested taking viagra because that's the only thing I know that can make you stay hard but I was wondering if there was another way. So I wanted to ask if any girl on here knows what to do or if they've been there?
