Well, I went from hidding my size as a kid using loose pants and tight underwear, to displaying in my late twenties and early thirties , to just wearing what i like, bulge or not. If the pants are fitted, then there is a bulge, and I usually don't care if folks look. In retrospect, in my swerious flaunting days, I think most folks just figured i had something stuffed in my jeans, swim trunks, whatever. Hell some may still think that.
If you like to show then go ahead. Just remember that every action has a reaction.
Here are some various photos of me, with varying bulges depending on my clothing.
