steroids related sexual problems

These days everybody talks about steroids. I know that they are not good, but there are people who say that they are not bad. I have a friend that is in all that stuff and now he have problems with his little guy (if you know what I mean). Is this type of thing common with steroids?

I am a bodybuilder (at least I consider myself one). I think everything is good (even steroids) in very small dosages. Overuse or misuse of it can make catastrophical consequences. Someone even think that supplements aren’t dangerous. Even their misuse (again and overuse) can be really bad for your health. And yes it can cause impotence. So if you aren’t smart, or a doctor, or haven’t a best friend who is a doctor (like I have), better stay of all steroids.
