Also just for clarification when I say bulge I don't mean when I'm excited just in general it looks like I got something I can't cover up.

My fashion advice would be wear looser shorts. Also, buy some t-shirts of singlets that cover it slightly so less attention is given to that area. These shirts should be more eye catching then the shorts so people's eyes are drawn towards the shirts and not bright shorts + the bulge.
You shouldn't be so worried about it, many guys try to make their 'bulge' look as big as possible. You don't even need to put any effort in to do that!
