I think maybe after I used a copy of a boxershort it resulted in a spot on my penis, if that is the case, is it dangerous? The spot hasnt grown either

Not sure. Not sure what the "copy of a boxershort" means, i'm afraid. Perhaps some mild trauma? Other things that can cause spots can be warts, some of which can be contagious. Even if it has not grown, it is likely best to let a health provider look at it to give the best answer.
