My right shoulder is sticking out...plz read details?

My right shoulder seems to be not in the right place, the anterior (front sureface of it( is really pointing outwards(pointing frontwards), i have to like flex and constantly adjust it to keep it in place...also bc of this my right romboid is pointing out as well...its really weird. Theres really no pain except when i really stretch out my shoulder/chest when doing the pec major stretch. Whats wrong with this and how do i fix it. P.S. i workout...maybe thats why?.. i also used to play basketball and my right arm was the dominant arm in that (lay-ups, dunks, shooting)
