Totally depends on HOW you wear a cup. If you wear one in the cup pocket of sliding shorts, it is going bulge out more than if you wear it "normally" (i.e. sliding shorts w/cup pockets were designed by women or something... 99% of them don't even work right. There is nothing to keep the cup snug against the body like it's supposed to fit. Hence, a cup in sliding shorts will bulge more.
Additionally, if your junk is so big that makes a cup bulge out, then your wearing it incorrectlly. The edges are supposed to be against your pelvis. That is what takes the blow (instead of your nuts) when you get hit. If your junk is making the cup bulge out (i.e. away from your pelvis), it totally defeats and real reason to wear one, and can actually do more harm than good if you take a shot there.
Well what you are saying is true about how the cup is worn. However, I know personally that some guys on our team have custom made cups from two main protective equipment companies. I dont like how some cups are so snug your junk cannot move around or be adjusted without getting pinched or squished. My point was that if your well endowed not all cups are going to fit correctly and for a couple guys on the team they dont fit exactly like they are supposed to. I know for me I like the jockstrap and cup combo but the damn cup doesnt always stay snug against my pelvis because Im constantly grabbing and adjusting because my twig and berries move around quite a bit.
