Only sometimes

My boyfriend has this problem where he can only get hard some of the time. IF hes alone, hes fine but once we are together things get more difficult for him, sometimes it works sometimes it doesn't. Is there any reason this would happen and would something like Viagra help him/us?

how old is he by the way
age has some thing to do some times

i have this problem wif one of my ex-gf
some how i could not get hard
was begining to worry till after we broke up
after that it has never happened

not saying it is her fault but some times it is stress ful to be wif her
(hope she is not read this)

maybe your bf is stressed up over some thing?
