I've seen pictures of people tucking where their genitals are almost %100 hidden, but I can't seem to quite do that. I've tried with some small women's underwear underneath some larger "tummy control" underwear that keeps everything from shimmying down, and it does a pretty good job, but there's still some bulge. My penis is small enough that it's not really an issue, but my testicles always seem to want to protrude. If I tuck them up and inward, they just make my whole pubic area bulge outward, and if I move them down more, they just protrude downward. I really don't think I have especially large genitals, and I thought they were on the smaller side, so is there some trick I'm missing? Or do I just have unrealistic expectations, or an unrealistic idea of how flat cisgender women's downstairs areas actually are?
