I have bony Shoulders?

My experience has been that you need to do heavy weights low reps like the other responder said. However, do not, repeat DO NOT, do them 5 days a week. Your muscles do their growing when they are resting/recovering. Training any muscle 5 days a week is silly. When you lift weights you are actually making micro-tears in the muscle. The only time these tears heal is when they get to rest. Also, switch up your lifts. In other words, don't just do the same lift all the time. Make sure to work all of your muscles equally. For example, if all you train is your upper body you will wind up looking like a mosquito. Eat clean, get lots of rest and do not get into steroids or HGH. That crap will kill you. Oh yeah, push ups are great for shoulders too. Good luck. Remember, men do not reach their physical peak, on average, until they hit 28 years old.
