My belt is not bigger than a cage, at least not where it matters. On the contrary, no more need for male underware with my belt because there is no more bulge in the crotch. The main difference is that a CB front shield has sharper edges than a high quality cage. Thus the risk of sore spots increases if the underweare is no thin and flexible.

      The difference from the little I know is about weight. A metal cage adds so e weight and that pulls on the testicle behind which the anchoring ring is locked.
      This can get very uncomfortable or even painful, so cage wearers usually prefer underwear that supports the weight of the cage.
      For belts regarding underwear there is not much difference between men and women - whatever floats your boat and hides the belt well enough.

        so you don't wear any extra underwear since you switched from the cage to the belt?

                      Pantyhose or tights hide them well.

                        My Neosteel Fun creates a fairly flat profile in front, so my typical men's briefs end up being a little baggy in that area. I find that some support is nice for the testicles since there is no shield on the Fun, I did some searching and found some women's briefs that provide good support, do not look feminine in any particular way and they are comfortable. I didn't want something feminine and I knew I was unlikely to find something that fits closer in that area in a men's variety, so these worked out pretty well.
