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.
