Can a person suffering lead a normal married life without getting wife into frustration? Yes.

What should wife and husband do to make their life better in such cases? My closest friend's husband suffers from ED caused by his blood pressure medicine. They use toys and find other ways to give each other pleasure. He tells her all the time how beautiful she is and let's her know that the ED isn't about her or his desire for her.

Does it reduces sexual urge? From what they've told me no it does not reduce his urges.

If a guy is just happy with blowjob from a girl and never tries to f*** her, does he has some problem? I'd say that's a different problem
