From our perspective we can't be prettier than a GG. However, what makes you think a GG can't be jealous of us, maybe there's some aspect of our looks? Why do the wives of cross-dressers sometimes place stipulations that the CDer can't dress or look prettier than the wife?
If that's the case than does this mean that a transgender man can never be more macho or manly than a cis-gendered man?
