I just learned from my friend that some tailors actually ask their clients how they like to “hang” so that they can design pants around the shape of their junk. Sooo yes, it is normal for there to be extra space when you don’t have one of them things. Some folks like to pack to make the fit look more natural. But that’s completely personal.
Generally speaking, skinny-fit jeans are going to have less room in the crotch. And, as A.D. pointed out, men’s jeans are designed to sit lower on the hips. Experimenting where you let them fall might help with the noticibility of the extra space.
Even if you can’t get rid of that space, don’t be insecure! (Bam, did I make it better?) If the jeans fit in every other way, that is a huge accomplishment. I bet they look awesome on you. So just rock ‘em, and don’t worry about it. A little crotch room never hurt anyone.
